Abstract:
VRLA (valve-regulated lead-acid) and Pump-control are the two kinds of power components for hydraulic servo system. With different command device, feedback measurement device and different corresponding electronic components, the hydraulic servo systems are different. To ensure maximum performance of the whole device, the overall design (including mechanical, electrical design) should be considered for hydraulic servo system. Machinery-electric-hydraulic should be in coordination with each other. The hydraulic system components are used to change the speed of hydraulic cylinder and alter direction of hydraulic cylinder and hydraulic motor. The solenoid valve for motor and hydraulic servo system and the control of pressure relay can implement by the electric section.

Abstract:
Electro-Hydraulic pump-controlled servo systems that have high energy-efficiency can serve as energy-saving system. This paper aims to investigate the servo performance of the electro-hydraulic pump-controlled systems driven by an AC servo motor with variable rotational speed. A constant displacement axial piston pump is used in this research. Thus, the new hydraulic pump-controlled system with an AC motor servo and a constant displacement axial piston pump is investigated for position control of hydraulic servo machines. For that, this paper also develops the control strategy, sign-distance fuzzy sliding mode control, which can simplify the fuzzy rule base through the sliding surface. The developed high response variable rotational speed pump-controlled systems controlled by SD-FSMC are implemented and verified experimentally for positioning control in different stroke and loading conditions.

Abstract:
This paper deals with a hydraulic servo system with compliance control for the operation in an environment with frequent machine-human interaction. The compliance is mechanically adjusted in the present hydraulic system by changing the neutral position of the bridge valves between the full opening and the full closing states. The mathematical model of the system is first derived, and the static and the dynamic behavior of the system are investigated through numerical simulation. Since the present system exhibits a strong nonlinear characteristic in the operating condition of large compliance, a nonlinear controller is designed with the feedback linearization technique. In the operating condition of small compliance, on the other hand, a conventional linear control is applicable as usual hydraulic control systems. The performance of the present control system is investigated through both numerical simulation and experiment, justifying that the present hydraulic servo system continuously adapts its performance between a rigid positioning against disturbances and a compliant positioning to prevent damage to obstacles on the path.

Abstract:
With the wide application of hydraulic servo technology in control systems, the requirement of hydraulic servo position control performance is greater and greater. In order to solve the problems of slow response, poor precision, and weak anti-interference ability in hydraulic servo position controls, a Kalman genetic optimization PID controller is designed. Firstly, aiming at the nonlinear problems such as internal leakage and oil compressibility in the hydraulic servo system, the mathematical model of the hydraulic servo system is established. By analyzing the working characteristics of the servo valve and hydraulic cylinder in the hydraulic servo system, the parameters in the mathematical model are determined. Secondly, a genetic algorithm is used to search the optimal proportional integral differential (PID) controller gain of the hydraulic servo system to realize the accurate control of valve-controlled hydraulic cylinder displacement in the hydraulic servo system. Under the positioning benchmark of step signal and sine wave signal, the PID algorithm and the genetic optimized PID algorithm are compared in the system simulation model established by Simulink. Finally, to solve the amplitude fluctuations caused by the GA optimized PID and reduce the influence of external disturbances, a Kalman filtering algorithm is added to the hydraulic servo system to reduce the amplitude fluctuations and the influence of external disturbances on the system. The simulation results show that the designed Kalman genetic optimization PID controller can be better applied to the position control of the hydraulic servo system. Compared with the traditional PID control algorithm, the PID algorithm optimized by genetic algorithm improves the system’s response speed and control accuracy; the Kalman filter is a good solution for the amplitude fluctuations caused by GA-optimized PID that reduces the influence of external disturbances on the hydraulic servo system.

Abstract:
In this master thesis, a mathematical model of a hydraulic servo system for a manipulator robot is completed by using several different methodologies. The models proposed are particularly tuned for the DeLaval VMS robotic arm. The parameter identification of the robotic arm is accomplished by dividing the model into several subsystems and investigating each system separately by using catalogue data, experimental data and construction drawings. Furthermore, the assumptions are proposed based on the literature review and the expertise of in-house engineers. After completion of parameter identification several different mathematical models including linear and nonlinear methodologies are introduced. It is demonstrated that the improvednonlinear model can successfully mimic the movement of the robotic arm with relatively small errors and it is found to be fairly reliable. Moreover, the errors incurred when chamber pressures are compared with experimental data are found to be relatively small. Furthermore, the improved linear model have successfully delivered an accurate position estimation especially for the medium valve opening, while the chamber pressures are relatively less accurately predicted. The study further carries out sensitivity (uncertainty) analyses to investigate the crucial parameters of the model since it is sometimes very problematic to precisely estimate these parameters. It is found out that the flow coefficient and supply pressures have remarkable impact on the results of the simulations. Therefore, it is strongly advised that these parameters should be very carefully evaluated during the modeling process. Finally the bulk modulus models are compared and the influence of the bulk modulus is revealed.

Abstract:
In many applications, the use of hydraulic drives is still preferable to other driving powers. For instance, in shaking table systems for simulating earthquake signal, hydraulic actuators are still widely applied, because the technology of electrical actuators does not(yet) provide the superior performance of hydraulic actuators in generating high power to weight ratio. However, with increasing demands on the performance of complex motion systems, the limits of performance of hydraulic servo-systems, due to the nonlinear and dynamic characteristics of these systems, come into the picture. Most nonlinearities of these systems arise from compressibility of the hydraulic fluid, the complex flow properties of the servo-valve, valve overlap and friction in the hydraulic cylinder. Aside from the nonlinear nature of the hydraulic dynamics, there are many considerable model uncertainties, such as internal and external leakages and external disturbances which cannot be modeled exactly. Therefore, in order to design a high performance controller for simulating the earthquake signal which is the goal of a servo-hydraulic shaking table, a suitable dynamical model of the system needs to be formulated. In this thesis beside a specific application of hydraulic actuator, a shaking table servo system, an integrated approach to the modeling and control of a hydraulic servo system is presented. The application of servo-hydraulic shaking table shows that the dynamics and nonlinearities of the servo-valve and the compressibility of hydraulic oil which basically constitute the limits of the performance of the controlled servo-system. Especially, in case of acceleration model and control of a hydraulic servo-system. In the shaking table application, for modeling and identification of the system, in contrary of the previous works which in them position and pressure sensors are used, only the position and acceleration sensor are available. In order to obtain structural insight in the way that the performance is limited by the properties of (the subsystems of) the hydraulic servo-system, the modeling of this system has been treated thoroughly in this thesis. At the one hand, this has opened the way to model-based control design, so that unavoidable limits of performance can be narrowly approached. At the other hand, the obtained insight appears to be useful in the system design stage, such that potential control problems may be avoided by proper system design. Because of the twofold purpose of the modeling, with control design requiring quantitatively accurate models and simulating the behavior of the system precisely which requiring qualitative insight in the system behavior, the so-called grey-box modeling approach has been applied. This approach comprises physical modeling including model analysis by means of simulation, and subsequent identification and validation of the obtained physical models, using experimental data. In the physical modeling stage, a consistent integration of the nonlinear dynamic modeling of the different subsystems of the hydraulic servo-system, namely servo-valve and actuator are presented. In this model, the most nonlinearities of the system which arise from compressibility of the hydraulic fluid, the complex flow properties of the servo-valve, valve overlap and friction in the hydraulic cylinder are simulated. Four different kinds of friction model are considered and the accuracy of these models for simulating the behavior of the system are compared experimentally. However, due to the limitation of these models in high velocity and bandwidth, it has been shown that for simulating the behavior of the system, nonlinear modeling of the friction is not enough. Then, by gathering some position and acceleration information of the real system, the sensitivity of the model to different nonlinearity of the system are investigated. This led to the insight, that only some of the modeled nonlinear effects are really relevant, such as the nonlinear flow characteristic of the servo-valve spool due to non-ideal port geometries and the compressibility of hydraulic oil, and the position dependence of the actuator dynamics. Based on the experimental results, two new nonlinear dynamic models for simulating the behavior of the servo-hydraulic shaking table are proposed. First, with defining 6 main parameters of the model and identifying them for different sinusoidal inputs, a neural network model is proposed. Second, a new empirical nonlinear model for effective bulk modulus of hydraulic oil is proposed which increase the accuracy of the model to predict the behavior of the position and acceleration output of the system. In this approach, the link between the physical and the system theoretic interpretation of the properties of the hydraulic servo system are strongly emphasized. This makes, that the presented models are not only useful for shaking table design, but also for the design of the hydraulic servo-system. Based on the task specification of the shaking table which is tracking the position and velocity reference signals with considering uncertain load conditions, different kinds of robust controller design are presented. For control designing purpose, the full order dynamic model of the system is simplified in a new approach and then due to the availability of only the position sensor on the experimental setup, a robust sliding mode observer is designed which can estimate the velocity and acceleration states of the system from the position sensor. Finally, experiments with a hydraulic actuator in a single degree-of-freedom setup have shown the validity of the approach for control design. The experimental results of the closed loop system controlling by three different controllers (feed forward PI controller, sliding mode and super twisting controller) with considering different load condition and reference signals are presented. An analysis of different control strategies for this setup led to the conclusion, that super twisting sliding mode controller shows a smaller error and smother response for position and velocity trajectory tracking with respect to sliding mode and feedforward PI controller.

Abstract:
The work presented in this paper aims at developing a hydraulic actuation system for an ankle exoskeleton that is able to deliver a peak power of 250 W, with a maximum torque of 90 N.m and maximum speed of 320 deg/s. After justifying the choice of a servo hydraulic actuator (SHA) over an electro hydrostatic actuator (EHA) for the targeted application, some test results of a first functional prototype are presented. The closed-loop unloaded displacement frequency response of the prototype shows a bandwidth ranging from 5 Hz to 8 Hz for displacement amplitudes between +/-5mm and +/- 20mm, thus demonstrating adequate dynamic performance for normal walking speed. Then, a detailed design is proposed as a combination of commercially available components (in particular a miniature servo valve and a membrane accumulator) and a custom aluminium manifold that incorporates the hydraulic cylinder. The actuator design achieves a total weight of 1.0 kg worn at the ankle.

Abstract:
L'évolution vers les avions plus électriques engendre des efforts importants pour développer des actionneurs à source de puissance électrique pour les commandes de vol. Pour de telles applications critiques, il est peut être intéressant dans le futur d'associer à une même surface de contrôle un actionneur conventionnel à source de puissance hydraulique et un actionneur à source de puissance électrique mais ceci pose un problème important lorsque les deux actionneurs sont actifs simultanément: comme chacun essaye d'imposer sa position à l'autre,les deux actionneurs luttent l'un contre l'autre en développant des efforts néfastes qui ne sont pas utilisés par la charge. L'objet du présent travail est de proposer des stratégies d’égalisation d’effort pour un système d'actionnement impliquant ces deux types d''actionneurs opérant en mode actif-actif. La première étape est de concevoir leur commande en position et de la valider sur banc d'essai. Un banc d'essai virtuel fidèle à la réalité est ensuite réalisé dans l'environnement de simulation AMESim pour pouvoir évaluer facilement les différentes stratégies d'égalisation d'effort entre les deux actionneurs. Ces stratégies sont proposées et évaluées virtuellement en deux étapes, statique puis dynamique. Pour finir, une étude de robustesse est réalisée a posteriori pour évaluer la sensibilité des indicateurs de performance aux incertitudes sur les modèles de simulation et sur les points et les conditions de fonctionnement
On the way to more electric aircraft (MEA), more and more power-by-wire (PBW) actuators are involved in the flight control system. For a hybrid redundant actuation system composed by the conventional hydraulically powered actuators and the PBW actuators, one major issue while they operate on active/active mode is the force fighting between channels. As the grave influence of force fighting on accelerating material fatigue and increasing power consumption,it must be addressed with attention. This thesis was aiming at proposing some effective force equalization control strategies for the hybrid actuation system involving one servo-hydraulic actuator (SHA) and one electro-mechanical actuator (EMA). For this objective, the position controllers for SHA and EMA were designed and validated as a first step. Then, a virtual test bench regarding to the realistic behaviors was built in the AMESim simulation environment to accelerate the controller design and enable the robustness study. Following this, 2 static force equalization control strategies were proposed and experimentally validated. The first strategy hat introduced integral force fighting signal to compensate the actuator position control was proved a good candidate solution. In the next part, 3 dynamic force equalization strategies were proposed and assessed on the virtual test bench. Their performance sensitivities to the parameter uncertainties were studied through Monte-Carlo method. The first strategy that introduced velocity and acceleration feed-forwards to force the SHA and EMA having similar pursuit dynamics showed a good force equalization performance as well as good segregation and good robustness. In the end, the work presented in thesis was concluded and perspective was given to the ongoing work

Abstract:
Linear Incremental Hydraulic Actuators combine one or more short-stroke cylinders, and two or more engaging/disengaging mechanisms into one actuator with long, medium, or even unlimited stroke length. The motion of each single short-stroke actuator concatenated by the engaging/disengaging mechanisms forms the motion of the linear incremental hydraulic actuator. The patterns of how these motions are concatenated form the gaits of a specific linear incremental hydraulic actuator. Linear incremental hydraulic actuators may have more than one gait. In an application, the gaits may be combined to achieve optimal performance at various operating points. The distinguishing characteristic of linear incremental hydraulic actuators is the incremental motion. The term incremental actuator is seen as analogous to the incremental versus absolute position sensor. Incremental actuators realize naturally relative positioning. Incremental motion means also that the behavior does not depend on an absolute position but only on the relative position within a cycle or step. Incremental actuators may realize discrete incremental or continuous incremental motion. Discrete incremental actuators can only approach discrete positions, whereby stepper drives are one prominent example. In contrast, continuous incremental actuators may approach any position. Linear electric motors are one example of continuous incremental actuators. The actuator has no inherent limitation in stroke length, as every step or cycle adds only to the state at the beginning of the step or cycle and does not depend on the absolute position. This led to the alternative working title Hydraulic Infinite Linear Actuator. Linear incremental hydraulic actuator provides long stroke, high force, and linear motion and has the potential to decrease the necessary resource usage, minimize environmental impact, e.g. from potential oil spillage, extend the range of feasible products: longer, stiffer, better, etc. This thesis presents an analysis of the characteristics and properties of linear incremental hydraulic actuators as well as the gaits and possible realizations of some gaits. The gait for continuous, smooth motion with two cylinders is comprehensively studied and a control concept for the tracking problem is proposed. The control concept encapsulates the complexity of the linear incremental hydraulic actuator so that an application does not have to deal with it. One other gait, the ballistic gait, which realizes fast, energy-efficient motion, enabling energy recuperation is studied.

Abstract:
This thesis presents an investigation of braking system characteristics, brake system performance and brake system component design parameters that influence brake pedal force / displacement characteristics as ‘felt’ by the driver in a passenger car. It includes detailed studies of individual brake system component design parameters, operation, and the linear and nonlinear characteristics of internal components through experimental study and simulation modelling. The prediction of brake pedal ‘feel’ in brake system simulation has been achieved using the simulation modelling package AMESim. Each individual brake system component was modelled individually before combining them into the whole brake system in order to identify the parameters and the internal components characteristics that influence the brake pedal ‘feel’. The simulation predictions were validated by experimentally measured data and demonstrated the accuracy of simulation modelling. Axisymmetric Finite Element Analysis (using the ABAQUS software) was used to predict the behaviour of nonlinear elastomeric internal components such as the piston seal and the booster reaction disc which was then included in the AMESim simulation model. The seal model FEA highlighted the effects of master cylinder and caliper seal deformation on the brake pedal ‘feel’. The characteristics of the brake booster reaction disc were predicted by the FEA and AMESim simulation modelling and these results highlighted the importance of the nonlinear material characteristics, and their potential contribution to brake pedal ‘feel’ improvement. A full brake system simulation model was designed, prepared, and used to predict brake system performance and to design a system with better brake pedal ‘feel’. Each of the brake system component design parameters was validated to ensure that the braking system performance was accurately predicted. The critical parameter of brake booster air valve spring stiffness was identified to improve the brake ‘pedal ‘feel’. This research has contributed to the advancement of automotive engineering by providing a method for brake system engineers to design a braking system with improved pedal ‘feel’. The simulation model can be used in the future to provide an accurate prediction of brake system performance at the design stage thereby saving time and cost.

Abstract:
Direct Driven Servo Hydraulic Actuator also known as Pump Direct Driven Cylinder (PDDC) represents a decentralized modern concept of energy efficient cylinder control without damping loses of direction valves. Such systems have many advantages over conventional hydraulic systems and combine benefits of hydraulic and electric drives. PDDC system developed in Laboratory for Oil Hydraulics at University of Maribor consists of hydro motor, which is used as a reversible pump that is directly driven by servomotor and is designed for experimental testing with differential hydraulic cylinder. In this paper, the aforementioned system runs experimental setup for force control of hydraulic cylinder, with load produced by pneumatic bellow.
