Dutto, Rémy. „Méthode à deux niveaux et préconditionnement géométrique en contrôle optimal. Application au problème de répartition de couple des véhicules hybrides électriques“. Electronic Thesis or Diss., Université de Toulouse (2023-....), 2024. http://www.theses.fr/2024TLSEP088.
Der volle Inhalt der QuelleMotivated by the torque split and gear shift industrial problem of hybrid electric vehicles, this work mainly proposes two new indirect optimal control problem methods. The first one is the Macro-Micro method, which is based on a bilevel decomposition of the optimal control problem and uses Bellman’s value functions at fixed times. These functions are known to be difficult to create. The main idea of this method is to approximate these functions by neural networks, which leads to a hierarchical resolution of a low dimensional optimization problem and a set of independent optimal control problems defined on smaller time intervals. The second one is a geometric preconditioning method, which allows a more efficient resolution of the optimal control problem. This method is based on a geometrical interpretation of the Pontryagin’s co-state and on the Mathieu transformation, and uses a linear diffeomorphism which transforms an ellipse into a circle. These two methods, presented separately, can be combined and lead together to a fast, robust and light resolution for the torque split and gear shift optimal control problem, closer to the embedded requirements

Der volle Inhalt der QuelleThis doctoral work focused on the study of the process involved in the control of a joystick-type device of interaction and had a double objective. First, this work was aimed to understand how the user of a device adapts its behavior to face a set of encountered constraints. In particular, the constraints inherent to the task (the index of difficulty and behavior of the object displaced) and the physical properties of the device (joystick or rotorcraft stick) have been manipulated. Second, understanding how the subject's behavior emerges from the influence of this set of constraints informed us about how we can access to a more intuitive control of the device and a better performance level. To achieve this goal, an analysis framework allowing the manipulation of all the constraints in conditions that are close to real situations of control (e.g. video-assisted surgery, aeronautics and industrial control) has been proposed. The behavioral analysis at two levels (local level and global level) that is used required the integration of concepts, means and methods from behavioral sciences (motor control) and from biomechanics. Taking all the results together, the study of the control process of a device of interaction allows a more general understanding of the perceptual-motor behavior

Der volle Inhalt der QuelleIn this thesis, we perform a study on a self-reacting point absorber, project FUI 12 “EM BILBOQUET”, in order to optimise energy extraction from incoming waves. Main researches use seabed for providing reference to a floating body, called buoy. However, as it is well-known that ocean energy is greater far away from the shore, sea-depth becomes a constraint. In this thesis a damping plate attached to a spar keel is proposed to allow the floating body to react against it. Energy resulting from the relative motion between the two concentric bodies i.e. the buoy and the spar is harnessed by a rack-and-pinion, which drive a permanent magnet synchronous generator through a gearbox. In the first part of the thesis we have developed a wave-to-wire model i.e. a model of the whole electro-mechanical chain from sea to grid. To this purpose we have developed our own hydrodynamic code, based on linear potential theory and on a semianalytical approach, solving the seakeeping problem. The hydrodynamic coefficients obtained such as added mass, radiation damping, and wave excitation forces are required for solving the dynamic equation based on Cummins formulation. The second part of the thesis focuses on the self-reacting point-absorber optimal control strategy and the Model Predictive Control (MPC) formulation is proposed. Objective function attempting to optimise the power generation is directly formulated as an absorbed power maximisation problem and thus no optimal references, such as buoy and/or spar velocity, are required. However, rather than using the full-order WEC model in the optimisation problem, that can be time-consuming due to its high order, and also because of the linear assumptions, we propose the use of a “phenomenologically" one-body equivalent model derived from the Thévenin’s theorem

Der volle Inhalt der QuelleIn this thesis, we address two problems of stochastic optimal control. Each problem constitutes a different Part in this document. The first problem addressed is very precise, it is the valuation of American contingent claims and more specifically the American Put in the presence of discrete dividends (Part I). The second one is more general, since it is the proof of the existence of a dynamic programming principle under expectation constraints in a discrete time framework (Part II). Although the two problems are quite distinct, the dynamic programming principle is at the heart of these two problems. The relationship between the value of an American Put and a free boundary problem has been proved by McKean. The boundary of this problem has a clear economic meaning since it corresponds at all times to the upper limit of the asset price above which the holder of such an option would exercise immediately his right to sell. The shape of the boundary in the presence of discrete dividends has not been solved to the best of our knowledge. Under the assumption that the dividend is a deterministic function of asset prices at the date just before the dividend payment, we investigate how the boundary is modified. In the neighborhood of dividend dates and in the model of Chapter 3, we know what the monotonicity of the border is, and we quantify its local behavior. In Chapter 3, we show that the smooth-fit property is satisfied at any date except for those of the payment of dividends. In both Chapters 3 and 4, we are able to give conditions to guarantee the continuity of the border outside dates of dividend. Part II was originally motivated by the optimal management of the production of an hydro-electric power plant with a probability constraint on the reservoir level on certain dates. Using Balder'sworks on Young's relaxation of optimal control problems, we focus more specifically on their resolution by dynamic programming. In Chapter 5, we extend results of Evstigneev to the framework of Young measures. We show that dynamic programming can be used to solve some problems with conditional expectations constraints. Through the ideas of Bouchard, Elie, Soner and Touzi on stochastic target problems with controlled loss, we show in Chapter 6 that a problem with expectation constraints can be reduced to a problem with conditional expectation constraints. Finally, as a special case, we show that the initial problem of dam management can be solved by dynamic programming

Der volle Inhalt der QuelleThe technique of averaging is an effective way to simplify optimal low-thrust satellite transfers in a controlled two-body Kepler problem. This study takes the form of both an analytical and numerical investigation of low-thrust time-optimal transfers, extending the application of averaging from the two-body problem to transfers in the perturbed low-thrust two body problem and a low-thrust transfer from Earth orbit to the L1 Lagrange point in the bicircular four-body setting. In the low-thrust two-body transfer, we compare the time-minimal case with the energy-minimal case, and determine that the elliptic domain under time-minimal orbital transfers (reduced in some sense) is geodesically convex. We then consider the Lunar perturbation of an energy-minimal low-thrust satellite transfer, finding a representation of the optimal Hamiltonian that relates the problem to a Zermelo navigation problem and making a numerical study of the conjugate points. Finally, we construct and implement numerically a transfer from an Earth orbit to the L1 Lagrange point, using averaging on one (near-Earth) arc in order to simplify analytic and numerical computations. In this last result we see that such a `time-optimal' transfer is indeed comparable to a true time-optimal transfer (without averaging) in these coordinates
