Full textThe building field is responsible of about 40% of global energy consumption and a third of world greenhouse gas emissions. It is a main concern subject in climate change issues and fossil fuel independency. The aim of the PhD work is to bring more knowledge about thermal modeling and to create specific tools which are capable of globally optimize the office building energy management. The industrial purpose is associated with its area of expertise, which is advice in energy and ecologic transition. It concerns the difficulty to implement a retrofit action planning. Indeed, for small or middle retrofit actions, the initial study and metrology costs represent over 50% of the overall cost. This down payment induces a long return of investment. Faced with this prohibitive financial parameter, a lot of companies are reluctant to implement this type of actions. The proposed purpose is a solution that drastically reduces preliminary costs. The aspects addressed in this thesis are: the building operation state of art and its associated issues, the creation of reporting and collecting data tool of building operation and performance thanks to a dedicated in-situ measurement network, concomitant with the development of a simplified adjoin thermal model. It facilitates the understanding of its behavior. Then the final aspect are the two steps of optimization. The first is the observable building design and operation parameters with an inverse method, the second is the calculation of optimal energy consumptions. The approach is specifically oriented through the development of tools allowing a facilitated access to energy reduction action for national companies. This should assist the integration of an intelligence for energy optimization for building climatics and thermal equipments or usage. The result could be a new ergonomic man-machine interface for stock building effective management. In the facts, the problem is holistic and cannot be handle sectorally. It is imperative to integrate all the process involved in the building and its use (user behavior). The approach have been oriented to take later into account other parameters than strictly energy, as costs of comfort

Full textThis work is focused on the real-time optimal control of a stand-alone system consisting of a photovoltaic generator, a PEM fuel cell, an alkaline electrolyzer, a battery and supercapacitor pack for a stationary application. The coupling of these different sources aims to improve performance, the availability of the resulting electrical grid, the supply of electricity over much longer periods, and especially the satisfaction of the load by using each source in a controlled way.First, a thorough study of the feasibility of the system from a technical, energetic, economic and environmental point of view is carried out. As a result, an optimal sizing method is proposed. A sensitivity analysis to evaluate the influence of subsystems cost and the size respectively on the overall energy cost and the equivalent CO2 emitted by the system is also discussed. Then, a model enabling easy scaling of components to achieve the capacity required for the system is developped. The global model of the system is obtained by exploiting the modularity of the formalism used for modeling (the Energetic Macroscopic Representation). Finally, an energy management method based on Energy consumption Minimization Strategy (ECMS) is proposed. A comparative study of the results obtained by the ECMS and those obtained by dynamic programming has enabled the validation of the optimal control strategy developed

Full textThe work presented in this thesis concerns the development of an optimization methodology for control laws of wastewater treatment plants. This work is based on the use of WWTP process models in order to simulate their operation. These simulations are used by a multi-objective genetic algorithm, NSGA-II. This optimization algorithm allows the search of optimal solutions when multiple objectives are considered (e. G. The effluent quality, energy consumption, etc. ). It also enables the visualisation of compromises arising between various control laws as well as their respective best domains of application. In a first part of this work, the optimization methodology in developed around four main axes: the conception of a robust simulation procedure, the choice of input datasets for the simulations, the choice of objectives and constraints to consider and the evaluation of long term performances and robustness of control laws. This methodology is then applied on the literature case study of BSM1. In a second part of the work, the methodology is applied on the real case study of Cambrai wastewater treatment plant. This application includes the development of new aspects like the generation of dynamic input datasets out of daily monitoring measurements of the wastewater treatment plant, as well as the simulation of control laws based on oxydo-reduction potential measurements. This application allowed to analyze the compromises between the control law currently tested on the wastewater treatment plant and a new control law foreseen. The benefits of this modification could hence be clearly observed

Full textThe porosity of a composite plate in carbon / epoxy of type RTM is known by used of tomography X. A method of determination of this porosity by measure of the mitigation of the longitudinal waves through the thickness of this kind of plate is proposed. These measures are made on surfaces of different sizes (from some cm2 to some mm2) and allow the obtaining of cartographies. A correspondence porosity (tomo X) - Mitigation (US wave) is deducted and analyzed according to the structure of the composite material. In every case, we estimate the quality of the obtained relations and we deduct the limits of validity of the correspondence between porosity and mitigation. First results of acoustic tomography are obtained

Full textThe main objective of this thesis is to propose frameworks and algorithms that are based on advanced control approaches, in order to guide cancer treatments scheduling. It also aims at pointing out the importance of taking into account the problem of stochastic uncertainties handling in the drug scheduling design, since cancer dynamical systems are considered to be highly uncertain phenomena.Cancer dynamical interactions are still an open research topic which is not fully understood yet. The complexity of such dynamics comes from their partially unknown behavior and their uncertain nature. Additionally, they are often described by nonlinear complex dynamics and require taking into consideration many constraints related to physiology as well as biology.In terms of control design, this topic gathers many complexity ingredients such asnonlinear dynamics, constraints handling and optimality issues. Therefore, in this thesis, we propose to use a recent optimal control approach that is based on moment optimization. This framework has the advantage of considering all the state and input variables as probability densities, allowing therefore to explicitly consider parametric as well as initial state uncertainties in the optimal control problem. We use this framework in Part II, in order to design robust optimal control schedules that represent cancer drugs injection profiles.The second problem that we address in Part III consists in the estimation of regionsof attraction for cancer interactions models. This problem is interesting in the context of cancer treatment design, since it provides the set of all possible initial conditions (tumor and patient health indicators), that can be driven to a desired targeted safe region, where the patient is considered to be healed. Furthermore, we focus on the assessment of methodologies that take into consideration the parametric uncertainties that can affect the dynamical model

Full textThis thesis deals with the study of the reconfigurable energy management of an electric vehicle based on the online identification of embedded sources. In recent years, the energy management of a hybrid system for automotive applications has been the subject of a great number of research. In this study, the energy chain considered consists of a fuel cell as the main source, storage sources such as batteries and/or supercapacitors, converters for each source and finally a load emulating the power demand. Indeed, the problem in hybrid systems is to find a strategy for a better distribution of electrical power between the different embedded sources, which is the added value of this research work. As well as defining energy management laws by considering real-time measurements in order to increase the lifespan and reliability of sources on the one hand, and the availability of the electric vehicle on the other hand. In this thesis, the nonlinear control called IDA-PBC (Interconnection and Damping assignment-Passivity Based Control) is used with the PCH (Port Controlled Hamiltonian) structure which allows to present structural properties of the system namely total system energy, damping and state interconnections. The IDA-PBC method is a powerful nonlinear technique, it is considered as a general means to stabilize a large class of physical systems. In a second part of this work, an optimal energy management strategy is proposed for the hybrid system under study, which is the combination of IDA-PBC and Hamiltonian's Jacobi Bellman method. Proof of stability is provided and the effectiveness of the proposed strategy is demonstrated. Several experimental validations are presented

Full textIn the current international context, companies need to be able to develop strategies to increase their performance and become more competitive. This rapidly changing environment introduces many uncertainties and constraints, making much more difficult to determine the best strategy according to the objectives set. The work developed in this thesis falls within this context and, more precisely, we are interested in the optimization of the control of production systems subject to uncertainties (such as machine failures) in order to minimize the overall costs. For modeling, the continuous-flow model is chosen to represent the material flow moving through the system. This model allows us to integrate transfer and transportation delays between the different components of the system. The analytical resolution method used is based on the sensitivity analysis methods and corresponds to the infinitesimal perturbation analysis method (IPA). This method allows us to deduce, based on learning from sample-paths, a gradient of the overall cost for each of the studies conducted. We prove that these gradients are unbiased, which allows us to use them in numerical simulations. The simulations allow us to determine the decision variables of control strategies of the studied systems. The control integrates the maintenance to the production. For the control of the considered systems, we also take into account constraints linked to the three pillars of sustainable development. These constraints are integrated into our models in terms of costs. Thus, the overall costs may not only include purely economic costs, but also environmental and social costs. We show that the proposed resolution approach may be used to optimize other objectives within a sustainability framework
