Full textMechatronics seems to be a source of organizational renewal as well as providing access to new markets characterized by the growing digitization of products and services. A question arises then: are organizations engaged in mechatronic design and production activity specific? And if so, within a broader context of Industrie 4.0, markedly digitized, can we provide a framework with guidelines that can be applied by the small and medium sized traditional mechanical organizations in order to position themselves in relation to this framework and consider to adopt a plan of actions and evolve towards mechatronics?This survey focuses on 5 noteworthy case studies that already have acquired a good mechatronic maturity level. The study enabled us to establish a relationship between the mechatronicity level of a product and the processes these organizations have put into practice in order to design and manufacture mechatronic products. More markedly yet, we have come to the conclusion that mechatronic products can be seen as levers to the creation of service offerings and thus push these companies to change their business models. We therefore propose that the latter should be managed by modern tools like the Business Motivation Model, for example. As the matter of fact, the BMM is a flexible and therefore suitable management tool for these mechatronic service oriented production systems (PSS). A service oriented architecture (SOA) of an organization then has to be planned, and we find that the business motivation model (BMM) is suitable for bridging these organizational architecture challenges.Specifically, we propose two practical and simple tools that can be seen as internal audit tools for any organization wanting to assess its competencies in mechatronics prior to plan future developments: on the one hand we elaborate metrics to assess the mechatronicity level of a product and a model assessing the mechatronic maturity level of the organization on the other.More broadly, this survey enables us to see mechatronics as a sequential evolution starting with a mechanical mono-domain product without communication abilities which develops to a multi domain digitized product communicating with other systems. The intermediate evolution phases are analogue basic electronic instrumentation, followed by digital electronics and embedded computing. The latter represents the real transition to mechatronics and drives the whole organization towards the digitization of its products and also its means of production and thus towards Industrie 4.0. This can also be seen as a proposal of a taxonomy of mechatronics

Full textMechatronic systems monitoring, especially those built on today's vehicles, is increasingly complicated. The interconnections of these systems for increased performance and comfort of vehicles increases the complexity of information needed for decision-making in real time. This PhD thesis is devoted to the problem of detection and isolation (FDI Fault Detection & Isolation) of faults in automotive systems using algorithms based on research and evaluation of information by mono-criterion approaches. Relevant variables for rapid detection of faults are selected in an automatic manner by using two different approaches: I. The first is to introduce the notion of conflict between all the measurable variables of mechatronic system and to analyze these variables using their projections in hyper-rectangles spaces classification. II. The second approach is to use Kolmogorov complexity as a tool for classification of fault signatures. The estimate of the Kolmogorov complexity by compression algorithms, without loss of information, allows defining a dictionary of faults and giving a score of criticality with respect to the healthy functioning of the vehicle. The two proposed approaches have been successfully applied to many types of automotive data in the ANR-DIAP project

Full textThe engineering of mechatronic systems requires the simultaneous and multidisciplinary design of the mechanical, electronic and software sub-systems. In this context, this thesis work is part within the framework on ``Conception Intégrée en Mécatronique Sûre de Fonctionnement''. The goal was to develop methods that allow and facilitate collaboration between people from different specialties in order to achieve a safe system for operation without setting a priori constraints on a system in particular. In the first section, we present a hot carrier induced MOSFET degradation model. We then describe the aging study of basic analog structures. We propose a design methodology to maximize the life of a circuit, and therefore micro-sensors, using the aging model. In the second part, taking as example a Miller OTA, we show how our method allows to design safe complex structures. To finish the manuscript we propose an original application of our design method: an analog aging sensor for CMOS integrated circuit

Full textThis research is developed in the field of architecture. It aims at studying the development of mechatronics in construction design and especially building sites. Mechatronics is a design process combining mechanics, electronics and informatics. It can be found in a lot of manufactured products, and is used in industry for production with the growth of robotics. The research in “Construction mechatronics” began in the early 70’s in japan. Later, the rise of rapid prototyping created new practices in architecture for “Design mechatronics”. It appeared in the early 2000’s thanks to the spread of CNC machining and microcontrollers in academic environments.These new practices and research fields are hardly observable in the construction industry. Mechatronics seems to be missing on building sites and not accessible. Also, Design mechatronics is not present in every design and technical departments. Thus, we focused on producing knowledges about the design processes attached to the integration of mechatronics in construction field. We did it by confronting this integration with a regular construction company activities.This led us to a series of experiments by case study in action-research. These cases are focussing on the concepts production for construction robotics. It involved multiple actors charged to the organisation and design of building sites. We looked at their reasoning to match mechatronics with their crafts and occupations.These studies had to be bound to scientific foundations. Architecture is not a scientific discipline, but can be related to Design sciences such as Architecturology developed in the MAACC laboratory. Design sciences helped us to analyse these observations and constitute design methods to design construction mechatronics systems
Ganet-Mattei, Florent. "Fabrication additive de matériaux électroactifs pour applications à la mécatronique." Thesis, Lyon, 2018. http://www.theses.fr/2018LYSEI011/document.
Full textAdditive Manufacturing (FA) is a manufacturing process that began to develop in the 1980s and is now mature enough to be used in a cost-effective and functional way by manufacturers. Additive manufacturing is defined as the process of shaping a part by adding material, as opposed to traditional shaping by material removal (machining). This new technology is a real revolution and enables us to meet new unprecedented technological challenges. Whether on a material axis or more widely as part of the plant of the future, additive manufacturing is a real growth driver, but many research work is yet to be conducted to perfect this new technology. It is around this issue that the work of theses focused with a focus on the integration of electroactive materials for the realization of mechatronics function taking advantage of Additive Manufacturing processes. Research shows that additive manufacturing of electroactive materials will be increasingly used for the realization of hybrid mechatronic functions that will combine both the mechanical structure, silicon integrated circuits, conductive tracks and printed coupled materials, integrating as well as features, such as sensors, displays or power sources. The work shows the potential application around the health control of composite structures, but also the instrument shape control for surgery. To arrive at the development of these devices, the following points have been developed around electroactive materials and their integration and optimization rules

Full textUroMems aims at developing a novel treatment solution for severe urinary incontinence by replacing the manual pump mechanism, which is currently considered as the gold standard and which is implanted in patients throughout the world, by a mechatronic device. An occlusive cuff that mimics the natural human sphincter is linked to the device in order to ensure continence and allow micturition.This work focuses on understanding and improving the artificial sphincter. The first part of this study aims at modeling of the occlusive cuff, characterizing the mechanical behavior of all of its components and establishing a corresponding finite element model. A bench test using digital image correlation is also presented in order to validate the behavior of the numerical model for a simple test. In the second part the implantation of the occlusive and its inflation are simulated and the model is validated by comparing its results to the data measured experimentally. The third part aims at validating the interaction between the occlusive cuff and an extraneous body in the numerical simulation. To this end the in vivo experimental behavior of the occlusive cuff is observed. The variability measured among the different subjects motivated the use of a phantom material (a Polyvinyl alcohol hydrogel) of controlled mechanical properties. A thorough mechanical characterization of the hydrogel is also presented in this part as well as a test bench used for the validation of the numerical model. The fourth part proposes a histo-morphological analysis of the male urethra and its mechanical characterization. The data obtained were then integrated to the finite element model. The last part of this work is dedicated to exploiting the finite element tool to propose design improvement of the occlusive cuff

Full textThe thesis' subject concerns the development of the control architecture and the trajectory generation for a scalable exoskeleton called SOL. The biomedical study outcomes revealed that the progressiveness of the disease could be solved by early and continuous rehabilitation throughout the growth. Thus, the importance of using an exoskeleton has a positive impact since it is used to provide locomotion and rehabilitation, at the same time. However, the current exoskeletons cannot be adapted to fit the continuous change of teenager biomechanics throughout his growth. Hence, the need for developing a scalable exoskeleton that can cope with the growing needs is still a challenging topic. Especially, the control architecture of such a scalable device was tackled in this thesis, in both hardware and software developments to incorporate the scalability features. Initiative steps have been passed towards the goal of achieving a scalable exoskeleton, by contributing in hardware developments that allowing further enhancements to be included throughout the advancement of the project. Firmware developments achieved have addressed the scalability needs in terms of control by considering the three hierarchical levels (which are: High, Middle, and low-levels of control). More specifically, a focus was dedicated to the generation of the gait reference trajectories for the growing population. Data were collected from healthy subjects wearing a passive exoskeleton to extract the proper joint trajectories, then, the data were processed to build a gait library to be deployed on the exoskeleton controller. Finally, by knowledge of the subject biomechanics, the controller is able to fetch the proper trajectories and inject the reference trajectories to the SOL's actuators. A first prototype of the exoskeleton is used to manifest the outcomes of the proposed Evolutionary Gait Generator (E.G.G.). As a first prototype, A free walking in air motion is tested, where the validation of the proposed hardware and control loops are demonstrated. Studying the exoskeletons' control responses against probable external disturbances and fail-safe scenarios are still future work mandatory before achieving first human-exoskeleton testing

Full textThe context of this PhD thesis is the modeling and design of mechatronic systems. The study is positioned in the early design stage of the conception cycle (V-Cycle), where the main efforts have to be produced in terms of methodology, to enhance the quality and the functionality of the products, and based on virtual prototyping (modeling and simulation). One of the possible methodology is to reformulate the design problem as an inverse problem, in order to directly use the design specification of the product, usually given in terms of the system outputs, and then solve the design problem. In this context, the Ampere laboratory of INSA Lyon has developed a conception and design methodology, based on inverse approach and using the bond graph formalism, to propose a step-by-step method based on dynamic and energetic criteria, with a structural analysis phase that allows hierarchical analysis steps, depending on the structural physical layout of the model (topological, phenomenological, parameter set). The aim of the present works is to contribute to the development of this methodology, by enhancing it to the class of descriptor systems. This choice is led by the aim to apply the methodology in the context of chassis design and vehicle dynamics, where, among other, multi-body models represented as a differential-algebraic equation (DAE) system could occur. The contributions are proposed at the level of the topology of the model, as well as at the level of the phenomenological / behavioral aspects. A preliminary step is to enhance the existing algebraic framework to support graphical extension (in term of digraph and bond graph). The overall methodological extensions allow, firstly, a generalization of the approach to the class of descriptor systems, and, secondly, to reach a standardization of the procedures, previously dedicated to direct or inverse models, so as no mandatory differences between those models have to be done anymore

Full textReliability analysis of mechatronic systems is one of the most dynamic fields of research. This analysismust be conducted during the design phase, in order to model and to design safe and reliable systems.After presenting some concepts of mechatronic systems and of dependability and reliability, we presentan overview of existing approaches (quantitatives and qualitatives) for the reliability assessment and wehighlight the perspectives to develop. The criticality of mechatronic systems is due, on one hand, to multi-domain combination (mechanical, electronic, software), and, on the other hand, to their different functionaland dysfunctional aspects (hybrid, dynamic, reconfigurable and interactive). Therefore, new approaches fordependability assessment should be developped. We propose a methodology for reliability assessment inthe design phase of a mechatronic system, by taking into account multi-domain interactions and by usingmodeling tools such as Petri Nets and Dynamic Bayesian Networks. Our approach also takes into accountepistemic uncertainties (uncertainties of model and of parameters) by using an evidential network adaptedto our model. Our methodology was applied to the reliability assessment of an "intelligent actuator" fromPack’Aero

Full textThe work presented in this memory is mainly devoted to the study of the continuous time generalize predictive control (CGPC) applied to mecatronic systems. It consists to a contribution to the analysis and the synthesis of a control law based on the minimization of a quadratic criterion. This control strategy is a well adapted control strategy, able to control a broad class of systems. Indeed, it applies as well to the unstable systems, as to the non minimum phase systems. An exact knowledge of the delay is not essential. Another scheme of predictive control was proposed, it consists in using the internal model control (IMC) based on CGPC minimization criterion. This method offers a good tracking trajectory to the CGPC, and gives the robustness benefits which the control structure offers. CGPC and IMC/CGPC robustness analysis made it possible to lay down some rules concerning the choice of adjustments parameters. Moreover, we examined the means of increasing the robust stability of the two algorithms, by using the concept of the LTR for the CGPC with observer, and by introducing a filter of robustness into the IMC/CGPC structure. In order to extend the predictive control to the nonlinear systems, a continuous time version of the Local Model Networks approach, based on the state space representation was proposed. Thus, a nonlinear control structure based on a balanced combination of CGPC regulators was established. Finally, another approach based on the combination between the predictive control and the sliding mode control CGPC/CMG is developed. This method showed its effectiveness and its performances in terms of static error almost null, and its regulation fastness in the presence of external disturbances. An experimental validation of the various algorithms was made on a three tanks system. The advantages as well as the limitations of the suggested control law were underlined

Full textHumanoid robotics actuation and control is complex as this field has specific needs. This involves the design of advanced mechatronic constructions. In this thesis, we focused on the humanoid robots actuation and paid particular attention to systems with good compliance capabilities. Compliance refers to the ability of the system to adapt to its environment by adopting a flexible behaviour. This feature is particularly sought after for human-robot interactions and to make contacts between the robot and its environment smoother. We studied two systems in detail : the first is a system based on Mckibben's artificial pneumatic muscles and the second is an electric cable driven actuator with flexibility. We have developed and implemented a control architecture for the control of both systems. The interest of this architecture lies in its generic nature and in its use within a model predictive control scheme. We then studied the thermal behaviour of an actuator in order to exploit the full potential of this system while ensuring its integrity. Finally, we have carried out developments to improve the joint torque control of the humanoid robot Talos

Full textThe purpose of this thesis is to study the effect of resins at the IML module (technology brought up by Valeo car supplier company), in the packaging of a mechatronic module with respect to its reliability under thermal cycling stress. This work consists of two complementary parts: the first part allows one to perform a macroscopic study in terms of volume through simulation of thermal effects in the module by using COMSOL software based on Finite Elements Method while the second part is devoted to the experimental study at interfaces at the microscopic level by ellipsometry technique. The simulation performed to determine the effect of the resin on the transport of heat in the module allows one to show that the presence of the polymer in the packaging tend to limit lateral temperature gradient which quench the mechanical stress of the chip on its support and the interconnexion material. The experimental study was performed in two steps: the characterization by ATG, ATR/FTIR and Brillouin scattering techniques, on the one hand, of the polymer alone and on the other hand, when it is in contact of different substrates (Si, CuNi, Al) characteristic of principal interfaces encountered in the module. Resistance to temperature rise has been quantified and a classification established by ATG technique. The presence of CO2 in the polymers has been evidenced by ATR and ellipsometry in the NIR and MIR. Particularly, it has been observed that a soft thermal stress coupled to a humid environment tend to increase the CO2 content in the polymers with the result that an increase in the volume of the polymer is expected, which may impact on its permeability as well as on its elastic properties as observed by the way by Brillouin scattering. A substrate-polymer interaction has been evidenced by ellipsometry on silicium and an interpreted in terms of siloxane bonding. Cu-Ni and Al substrates dont modify the polymers but in a humid atmosphere, on may note that temperature cycling results in modification of the optical properties of the polymers which are in contact with both substrates from the variation of their optical constants which is more important for Al than for Cu-Ni

Full textThis research concerns the development of a virtual reality platform for a differential drive mobility aid in manual or electric wheelchairs with multipurpose usage in an enabled environment. The platform for the mobility aid is stationary, with pitch and roll actuated actions for possible different uses such as: manual or electric wheelchair driving simulations, wheelchair training, assistive technology research, architectural route planning and accessibility evaluation. By means of the platform, the differential drive mobility aid, is greatly able to assist inexperienced users in this method of mobility training. The use of the developed mobility simulation platform is additionally of benefit to disabled wheeled mobility users in need of occupational therapist training and evaluation. The investigation into the mobility factor will moreover be of further benefit in the area of the ergonomic designs of architectural structures for wheelchair-bound users. The platform is a mechatronic design with both mechanical and electrical properties. The mechanical components consist of drums, driven by the wheelchair and its user when placed on the platform, where acquired data of the rotation of the wheelchair’s wheels are of importance. The platform is connected to actuators for simulating angular movements of the wheelchair approaching an inclining or declining given path. The simulator necessarily maps intended motion by an electric wheelchair user into the virtual world, taking into consideration influences such as collisions, gradient changes and different surface properties. Audio, motion and force feedback produced on the virtual mobility simulator give the users a sensory stimulus input with regard to sound, movement and balance. Ultimately, the design forms a unity, comprising a mechanical platform, the wheelchair and the enabled user, with the relevant kinematics and dynamics controlled in a simulated virtual reality environment

Full textThis work focuses on the multidisciplinary and collaborative design of integrated systems. These systems are subject to an ever increasing number of requirements, leading to the need for more comprehensive functional and spatial integration. These different types of product integration are also at the origin of organizational complexity. This complexity arises not only from the great number of actors performing various engineering activities but also from the diversity of disciplines involved (designated in this manuscript as “multidisciplinary integration”). To encourage this multidisciplinary integration, “preliminary design” and “detailed design” have been identified as the most significant steps, especially since they are characterized by the collaboration of multiple experts handling a large number of product definition’ technical data. Systems that have been designed thanks to multidisciplinary approaches are generally poorly integrated. This is partially due to the compartmentalization of disciplines, as well as to the “project-planned” method, where project planning is predominant and information is mainly spread out “top-down”. To ensure better cooperation between the various disciplines, to enable decision making based on operational indicators and to analyze and understand the multidisciplinary integration processes, a method inspired by the founding principles of agile methods (the agile manifesto) is proposed for the collaborative design of integrated systems. This work is based on three complementary concepts. The first is, the Collaborative Actions Framework, an operational framework for collaboration around actions. One objective of this framework is to improve the collaboration among designers, whatever their disciplinary origin. It also ensures traceability between decision making and corrections/changes made to technical data. This traceability is made possible by the useof the second concept, called Workspace. Even if this term is already well known, we propose a new definition/usage to transform it into collaboration spaces. This concept offers great possibilities, including the continuous delivering/sharing of experts’ contributions, multidisciplinary integration and change validation. The exchange of technical data between workspaces, or simultaneous work on the same data, relies on the ability to manage several parallel versions of the same item into a single datamanagement system. These opportunities are offered by the third concept, called Branch & Merge. Finally, these three concepts are illustrated through a scenario and a computer prototype. A mechatronic product, “the synergistic combination of mechanical and electrical engineering, computer science, and information technology” (Harashima et al., 1996), is used to illustrate the opportunities offered by our work in terms of multidisciplinary integration during collaborative design

Full textIn France, 460000 infants between one month and two years are affected by the acute bronchiolitis each winter. This viral infection which leads to an inflammation of the respiratory tract is generally treated during a respiratory physiotherapy(RP) session. In order to improve the technical learning of the paediatric RP, a simulator which represents a six month old infant with an average type of bronchiolitis was developed in the laboratory SYMME. This first simulator allows the physiotherapist students to learn the basic gestures of the RP in a didactic and safe environment. This research work follows the frame work of this study and should allow an improvement of the training by proposing various didactic situations. As a first step, a system that allows reproducing the breathing movement of an infant on the simulator was developed. Then we worked on the design of a mechanism that allows obtaining a variable mechanical behaviour of the thorax in order to enable the student to practice on different clinical cases. For the realisation of such a device, we focused on systems which are conventionally used to dissipate energy by modifying the stiffness and/or the damping of the structure. Two semi-active devices based on the usage of a cylinder/piston system were examined. They differ in the way the pressure difference between the two chambers of the cylinder is generated : first, by changing the flow geometry and second, by a modification of the fluid flow characteristics of a magnetorheological fluid. The first solution was partially validated by a physiotherapist but was not completly satisfying. The second solution was tested on a specific test bench and seems to be a promising way to realise a simulator with variable properties

Full textThis Master's thesis presents the design and experimental validation of a mechatronic system aimed at facilitating the handling of heavy components in industrial assembly situations, for example the assembly of aircraft fuselage panels. The principle of underactuated redundancy is used to make the interaction between the human operator and the robot safe, intuitive and responsive, while allowing a relatively high payload. This principle consists in using a low-impedance passive mechanism paired with an active system with a payload directly attached to the passive mechanism's end e ector. In the operation of the device, the human operator directly manipulates the payload and thereby induces movements in the passive mechanism. The measured joint variables in the passive mechanism are then used to control the high-impedance active joints of the robot. In previous works, the principle of underactuated redundancy has been applied to translational movements. The aim of this Master's thesis is therefore to apply the principle of underactuated redundancy to rotations in order to rotate a payload in three-dimensional space. First, the principle is applied to a one-degree-of-freedom planar manipulator in order to evaluate the validity of the concept for rotational motions. Then, it is applied to a two-degree-of-freedom spatial manipulator. Active counterweights are used to statically balance the two manipulators. It should be noted that the last rotational motion is not studied since it is easy to implement; static balancing is not required for the rotation around the vertical axis. Subsequently, the rotational system obtained previously is combined with an existing translational system with the objective of freely manipulating a payload in six-dimensional space. The experimental validations are presented to show that the manipulator is safe, intuitive and responsive for the human operator.

Full textThe pre-sizing takes place upstream to the process of designing a system: from a set of requirements, it consists in determining a set of possible technical solutions in an often very large search space which is structured by the uncertain and partial knowledge available about the future system and its environment. Long before making the final choice and the final sizing of the system components, the designers have to use specifications, models of the main phenomena, and experience feedbacks to formalize some constraints, make simplifying assumptions, consider various architectures and make choices based on imprecise data (i.e. intervals, finite sets of possible values, etc…). The choices made during the pre-sizing process often involving strong commitments for the further developments, it is very important to early detect potential inconsistencies and to verify the satisfaction of the requirements in an uncertain context. In this work, a methodology based on the exchange of set-membership models between principals and suppliers is proposed for the verification of requirements. This methodology is fully consistent with a design paradigm based on the reduction of uncertainties. After a work dedicated to the modeling of mechatronic systems, a special attention is paid to dealing with deterministic uncertainties affecting continuous values: some techniques based on interval analysis such as constraint satisfaction (interval CSP), reachability computations for knowledge dynamic models or identification of set-membership behavioral models are used and developed, so providing a set of tools to implement the proposed methodology and contribute to reach the goal of a verification with a full and guaranteed coverage

However, chattering (actuator high frequency vibration) is its major disadvantage. The main goal of this work is to find a solution to the chattering problem and rejected mismatched uncertainties. Firstly, we propose a new method to design a sliding surface for linear systems with mismatched uncertainties. The proposed sliding surface provides a new stability criterion of the reduced-order system origin with respect to mismatched uncertainties. Then, we proposed a new strategy of sliding mode control using the transfer function approach, this study relates to the second order linear systems. Secondly, in case of nonlinear systems, we have find a solution of chattering problem using variable structure control in the boundary layer, the stability and the robustness of the closed-loop system are proven analytically using the Lyapunov synthesis approach. In the presence of output noises, a robust differentiator via sliding mode transfer function is studied. The application of this method to Hydraulic system gives encouraging results which are presented on different case. Finally, we designed a sliding mode observer for system with unknown input in order to recover the information

Full textIn this thesis we proposed a method for the study of parametric variation for continuous and hybrid systems and an approach for mechatronics tolerancing. We first studied the different existing approaches to take into account the variation of parameters. For continuous systems with variable parameters we chose the method of differential inclusions. We took the Raczynski algorithm and we have developed an optimization algorithm which is based on the steepest descent method with an extension to obtain global optimum. For hybrid systems, containing continuous evolutions and discrete jumps, and have parametric variations, we have chosen the formalism of impulse differential inclusion as a modeling tool. We took this formalism and identified its components on a mechatronic system. We have developed algorithms for solving impulse differential inclusions for several variable parameters. To view the results, the developed algorithms were implemented in Mathematica. We ended this part by a comparison between our approach and others like those around hybrid automata invariant polyhedron, polygonal differential inclusions and practical algorithm for solving differential inclusion. We showed then some advantages of our approach. In the last part, we organized the different tools used and results obtained to define and refine our approach to tolerancing. We defined the area of the desired operation, the various scenarios that may present, and its intersection with reachable area. We presented a metric tool based on topological Hausdorff distance for the calculation of distances between the different sets. With these elements, we proposed an iterative approach to tolerancing in the state space

Full textThe thesis presented here, represents a first step in the development of an intelligent prosthetic system for the human upper limb, with low costs, at Timisoara. By determining the kinematic parameters of the prosthesis’ simplified model it is possible to predict its behavior and movement possibilities. Trough the representation of the active workspace and its projections in different planes, it is possible to observe, modify and optimize the laws of motion, respectively the trajectories of different kinematical joints controlled by the prosthesis’ microcontrollers. Starting from the study of the functional anatomy of the upper limb and the current state of development of prostheses worldwide, a prototype level intelligent prosthesis was designed and engineered for the upper limb. The developed prosthesis is functional and at a low cost. The mechanical components of the prosthesis’ structure consist of the shoulder, elbow and hand joints, bars and other linkage elements. The actuating system of the prosthesis is made with stepper motors and reducers. The sensorial system is formed by the control elements of the prosthesis and micro-switches. To demonstrate the functionality of the prosthesis, it was put under experimental tests to analyze the movements with systems based on video acquisition, ultrasound and vibration measurements during different tasks. The results of these experimental studies validate the prototype built by the author

Full textElectric machines play an important role in power conversion in several applications and fields. With the increasing demand for designing lighter and more efficient machines and optimizing the existing structures, thermal analysis becomes a necessary; in fact, the performance of electric machines islimited by the allowable temperatures in many critical components like windings, permanent magnetsand bearings. Two main approaches can be employed in order to study the machine thermal behavior : the lumped parameter thermal network (LPTN) or numerical models. Considering low-computationtime-consuming and the possibility to be integrated in a mechatronics system design, the LPTN method is considered in our study. The latter is mainly applied on electric machine integrated in a complex mechatronics environment. The thermal network is presented along with the definition of the principal elements constituting this network. In fact, an accurate and reliable network strongly depends on many critical parameters like heat transfer coefficients, interface gaps, impregnation goodness, among others. For this reason, different sensitivity analysis techniques are carried out in order to, first, identify the significance of uncertainties in the evaluation of these parameters on machine temperatures and second, to reduce the thermal network. Next, we propose two optimization algorithm-based identification methodologies in order to calibrate results of the thermal network with measured temperatures obtained from a test-bench of a permanent magnet based integrated starter-generator machine. The calibrated model is then integrated in a mechatronics system consisting of an electric model of the electric machine, along with its control strategy and the power converter. This final study allows us to evaluate the impact of the machine temperature rise on the mechatronic system

Full textDuring the design phase, the different engineering teams make multiple FE simulations dealing with various physical behaviours in order to ensure both verification and validation.However, the unsatisfactory results lead to late changes and hence to long iterations and increasing costs.In order to tackle this problem, it is essential to take into account the geometrical and multi-physical constraints in the complex system architecture since the conceptual design phase.In fact, a process called SAMOS is developed aiming at selecting the most adequate 3D multi-physical architecture while ensuring an efficient collaboration between the engineering teams. Moreover, this framework is based on two SysML extensions which allow the enrichment of the architecture with geometrical and multi-physical data.Furthermore, this thesis focuses on magnetic constraints and magnetic-thermal coupling.Since this phase does not support long FE simulations, the analytical models based on simplified geometries are sufficient to provide satisfactory approximate results.In this context, different analytical models are studied and validated through FE simulations and measures for several cases such as NdFeB permanent magnets. Indeed, the temperature rise does not only decrease the remanent flux density but is able also to cause irreversible losses. In fact, once we go back to the initial temperature, the characteristics of the magnet are modified. The different factors impacting the demagnetization process are discussed.Besides, the temperature impact on brushless motors’ performances is studied since this device represents a complex mechatronic system

Full textReliability analysis and design become indispensable for the development process of mechatronic systems. However, versatile tools are called for because of the increas•ing complexity and the testing expensiveness of mechatronic systems. Such complexity brings the difficulties of modeling uncertainty and unknown dependency, such as functional and temporal dependency. To deal with such complexity, reliability analysis tools need to be mathematically powerful, be easy to use and be computationally efficient.Conventional tools have a number of drawbacks when evaluating the reliability at system level. For instance, Markov chain based methods have a problem of infamous combinatorial explosion and fault trees formalism works under the assumption of component independency. Although sorne extensions, such as dynamic fault trees, have been made to make up for shortcomings, not all of them can be handled in one framework. Bayesian networks formalism is recently believed to be a promising statistical inference tool for system reliability assessment thanks to many advantages, such as the ability of modeling uncertain dependency, integrating data from diverse sources and the well-studied reasoning tools. On the other hand, the biggest value-added in mechatronics is in control/information processing subsystem. Engineers realize that the controller design of a dynamic system cannot neglect the dynamic reliability requirement. Various uncertainties influence not only the controller performance but also the reliability. However, little research has considered the dynamic reliability of controllers.In this research, we have investigated the Bayesian networks formalism and developed a new system reliability assessment method for complex mechatronic systems. This method extends Bayesian analysis on components to that on complex systems and allows to consider parameter uncertainties of various skewed time-to-failure models in complex systems. To perform the inference in our Bayesian network model, we developed a modified nonparametric beHef propagation which is more efficient in the complex case compared with other reasoning tools. We showed also how to perform the sensitivity analysis in our Bayesian network model that has a non-deterministic structure. A dynamic-reliable linear controller has been designed for the control module of mechatronic systems. We established a new link between the first-passage failure probability and controllers' feedback gains, and obtained a new dynamic-reliability constraint for classical objectives. The dynamic-reliable linear controller is also extended to the multiple model formalism for achieving a dynamic-reliable controller applicable to nonlinearjnon-Gaussian cases. The system performance can be further improved in this framework by using more advanced multiple model methods.A number of simulation results demonstrated that the developed methods have been successfully applied to analyze and design active vehicle suspension systems and can be applied to other applications, such as other mechatronic systems and active building control systems

Full textThis thesis deals with the design and realization of a dynamic mechanical platform intended to the motorcycle riding simulation. This dissertation is organized into several principal sections. First, a literature review is conducted to identify the driving simulation problematic in a general way by focusing on the simulator design. In this part, it was aware of the various mechanical architectures used previously as well as the related limitations. The choice of the simulator‘s mechanical architecture of is driven by the needs to have an sufficient perception during simulated driving situation. Our goal is to reproduce the most relevant inertial effects (acceleration, torque, ..) perceived in a real world driving. The second chapter discusses an exhaustive comparison between automotive vehicles dynamics against the two-wheeled vehicles against. Existing motorcycles dynamic models are adjusted and of have been adapted to meet our needs in terms of privileged inertial cues. The third chapter presents the design aspects, mechanical realization, characterization and identification of the motorcycle simulator developed within the framework of this thesis. It constitutes the main contribution of this research works. Finally, the last two chapters are dedicated to motion cueing /control algorithms and open-loop experimentation on the simulator’s platform. These tests were performed for the characterization and validation of performance of the entire simulation loop

Full textPlusieurs personnes vivent avec des incapacités qui affectent le contrôle du mouvement des membres supérieurs. Ces troubles de mouvement peuvent être présents sous forme de contractions involontaires, de mouvements spasmodiques ou de tremblements. Ceux-ci limitent ces personnes dans la réalisation de plusieurs tâches de la vie quotidienne. Des aides techniques peuvent alors servir à faciliter les déplacements, à compenser un manque de tonus musculaire ou à permettre la manipulation d'objets. Plus particulièrement, des aides techniques sont conçues pour les personnes vivant avec des troubles de mouvement aux membres supérieurs pour leur permettre de s'alimenter de manière autonome. Par contre, plusieurs facteurs limitent l'utilisation des aides techniques actuelles, tels que leur prix élevé ou leur complexité d'utilisation. L'objectif de ce mémoire est le développement d'une nouvelle aide à l'alimentation pour les personnes vivant avec des incoordinations motrices au niveau des membres supérieurs. L'hypothèse est que l'utilisation de l'aide à l'alimentation développée permettra d'améliorer la capacité des personnes avec des troubles de mouvement à s'alimenter de manière autonome. Cette assistance augmenterait l'implication de l'utilisateur lors des repas tout en réduisant la charge de travail des aidants ou préposés. Deux systèmes ont été développés : une version passive et une version active. La version passive consiste en un assemblage de barres qui maintiennent l'orientation de l'ustensile constante et amorti mécaniquement les mouvements brusques involontaires. Une version active a ensuite été développée, où des actionneurs remplacent les amortisseurs mécaniques, afn d'offrir une assistance plus intelligente.
Many people are living with neurological disorders such as cerebral palsy, stroke, muscular dystrophy or dystonia, that affect the control of upper limb movement. These motor disorders can be involuntary contractions, spasmodic movement or tremors. These disorders limit in the accomplishment of several tasks of daily life. Technical aids can then be used to facilitate movement, to compensate for a lack of muscle tone or to allow the manipulation of objects. In particular, assistive devices are designed for people with upper limb movement disorders to eat autonomously. Several factors limit the use of current assistive devices, such as their high price or high complexity. The aim of this thesis is the development of a new eating aid for people with upper limbs motor disorders. The hypothesis is that the use of the eating assistance developed will improve the ability of people with movement disorders to eat autonomously. This assistance would increase user involvement while reducing the workload of the caregiver. Two assistive prototypes have been developed : a passive version and an active version. The passive version consists of a bar assembly that maintains the constant orientation of the utensil and mechanically dampens involuntary movements. An active version was then developed, where actuators replace the mechanical dampers, in order to offer a more intellignent assistance.

Full textThis work anticipates that, in an ever-expanding digital technology world, technological breakthroughs in the analysis of data collected by spectroscopic devices will allow the almost instantaneous identification of known species observed in-situ in a specific environment, leaving the necessary in-depth analysis of unobserved species. The method derived from RBDO (Reliability Based Design Optimization) technology will be used to implement an artificial intelligence procedure to identify observed species from a mobile IR sensor. To successfully analyze the obtained data, it is necessary to appropriately assign molecular species from the observed IR data using appropriate theoretical models. This work focuses on the observation from mobile devices equipped with appropriate sensors, antennas, and electronics to capture and send raw or analyzed data from an interesting IR spectroscopic environment. It is therefore interesting if not essential to focus on symmetry-based theoretical tools for the spectroscopic analysis of molecules, which allows to identify the IR windows to be chosen for observation in the design of the device. Then, by fitting the theoretical spectroscopic parameters to the observed frequencies, the spectrum of a molecular species can be reconstructed. A deconvolution of the observed spectra is necessary before the analysis in terms of intensity, width and line center characterizing a line shape. Therefore, an adequate strategy is needed in the design to include data analysis during the observation phase, which can benefit from an artificial intelligence algorithm to account for differences in the IR spectral signature. In this regard, the analytical power of the instrument data can be improved by using the reliability-based design optimization (RBDO) methodology. Based on the multi-physics behavior of uncertainty propagation in the hierarchical system tree, RBDO uses probabilistic modeling to analyze the deviation from the desired output as feedback parameters to optimize the design in the first place. The goal of this thesis is to address IR observation window parameters to address reliability issues beyond mechatronic design to include species identification through analysis of collected data

For this reason,several humanoid robots make use of this technology to demonstrate performance in heavy-dutyactivities. Basically, hydraulic actuation is accompanied by leak problems linked to the presence ofhydraulic tubes. This research focuses on solvingthis problem by adopting two approaches. Adopting the first solution, internal parts are designedin a bio-inspired approach to drive pressurized oilto the actuated joints. All robotic parts are redeveloped in a shell design with integrated plastictubes, 3D printed, then molded with carbon composite material for strengthening. The second solution aims to create punctual power generationunits at the actuation joints. For this aim, a patented Servo Electro-Hydraulic Actuator is developed, modeled, and designed.

Full textThe design step of a complex system is crucial. This observation is particularly true, when considering mechatronic, multi-technological systems, which require a multidisciplinary and collaborative approach. Our work is based on the System Engineering (SE) framework, which focuses on the needs and requirements definition, the conceptual design, and the definition of functional and organic architectures of a system. For this purpose, SE promotes some concepts, processes, and an approach currently widely practiced in the Industry, and even standardized while being a much studied research topic. More precisely, we are interested in a so-called support process of SE, the evaluation process. We are focusing on the effectiveness evaluation and then on the comparison of different functional and organic architecture solutions of a mechatronic system, which emerge invariably from the design. The goal of this process in guiding and helping to choose a solution among candidate architectures, often incomplete or immature in preliminary design, allows maximizing the satisfaction of the systems' stakeholders needs. However, the implementation of this evaluation faces to many difficulties. The consensual and unified vision of data, information, knowledge, and evaluation activities, above specialized engineering teams involved in the design, is still limited. Indeed, the lack of this common vision limits the objective and shared evaluation of a given solution. This is a first problem that we are addressing in our work. To contribute to this common vision, a conceptual model of evaluation data in SE is proposed.Subsequently, the estimation of the choices made all along such an iterative design, and which therefore proceeds by small steps, the management of multiple objectives sometimes contradictory and the consideration of the uncertainty inherent to design are classic problems in design. This constitutes the main problem which our work is answering. The estimation of the consequences of design choices on the system performance is first addressed by a formalization of traceability links between the requirements, functions, and components of the design. This formalization is prior to the detection and correction of inconsistencies of traceability links, in order to automatically identify potential impacts of the architectures' elements choices on different satisfaction criteria of the System Of Interest (SOI). An articulation between the SOI behavioral models and decision models is afterwards proposed for aggregating the satisfaction level of the design objectives, and then ensure the management of multiple and even contradictory objectives of the designers. Qualitative evaluation techniques are finally proposed for sorting the alternative design solutions according to their satisfaction level while considering the increasing maturity level but uncertain of the solution.Lastly, we often denote the lack of integrated environment for modeling the system and proceeding to the analyses and evaluations. The two above synthesized contributions have been integrated into a SE framework, offering a continuum between design activities and evaluation ones. The result is thereby a methodological and tooled guide for mechatronic systems evaluation during design.

Full textNowadays, embedded systems are becoming increasingly attractive for many applications. Furthermore, these systems should be more and more dependable. Indeed, systems such as mechatronic or automatically controlled ones often work in harsh environmental conditions making them more prone to errors due to disturbances. Thus, designers should consider ways to protect them against such errors. In this work, a special interest is dedicated to processor architecture dependability as we consider processor-based systems. The stack computer philosophy has been chosen for the processor architecture in order to achieve a good trade-off between simplicity and effectiveness. Our approach to introduce and evaluate the dependability is based on the development and the use of a software emulator of the processor to be designed. Dependability of the processor is ensured through the collaborative use of hardware and software protection techniques: hardware error detection means and software error correction means. The correction technique is implemented in benchmarks and is validated on the emulator through a simulation of various scenarios of errors appearance. Different parameters are evaluated such as correction capability and time overhead. This correction technique is independent from the target application and from the detection means, what confirms the methodological aspect of our approach. Otherwise, as requested by the CIM’tronic project, we integrated our work with the CRAN Nancy/A3SI Metz one by applying the information flow approach on the processor instruction set. We showed the ability of this approach to evaluate the whole processor/application dependability

Full textThis thesis comes within the scope of mechatronic systems design and deals especially with the problem of their sizing. To that aim, it focuses on methods allowing the selection of the components constituting their actuating chains with respect to given requirements. Since current competitive rules require a frequent product renewal in spite of ever increasing product complexity, the adopted approaches for handling this kind of problem have to be less expensive in financial terms as well as in the duration of the design phase. So as to decrease the number of iterations during the design process, one possible is to reformulate the problem as an inverse problem where the unknowns of the sizing problem are directly determined from the requirements expressed on the system outputs. With that in mind, the laboratory Ampere suggests a sizing methodology based on the use of inverse bond graph models. The objective of this thesis is to contribute to the development of this methodology in its structural phase on one hand (i. E. Thes phase allowing to check before any numerical simulation if the inverse problem is well-posed) and in its sizing phase on the other hand (i. E. The phase where the model inversion is applied and exploited)
