Liang, Mincui. "Dynamic Wireless Charging System." Electronic Thesis or Diss., Université Clermont Auvergne (2021-...), 2024. http://www.theses.fr/2024UCFA0072.
Full textDynamic wireless power transfer is a promising solution for charging electric vehicles while driving. It is, however, technically challenging due to the loosely-coupled and dynamic nature of the system. To address this challenge, this thesis proposed a novel switching point control method to ensure a high and efficient power transfer for a wide range of coupling situations. The thesis took a deep dive into the series-series wireless power transfer and, from both design and control perspectives, thoroughly investigated all the technical aspects which could potentially affect the system performances in theory and practice.From the system design perspective, different theoretical modelling and calculation methods were first derived to compute, select and validate the key components of the system and their parameters. A holistic model-based parametric design and analysis approach was adopted to generate and evaluate design alternatives of the system against specified performance criteria.Consequently, an optimal design of the series-series wireless power transfer system was achieved with a close-to-one resonant frequency ratio and high performances for the wide ranges of coupling situations and operating frequencies. From the system control perspective, systematic analyses were first carried out to thoroughly understand the interrelations between the operating frequencies and output power and identify the optimal frequencies which could be potentially utilised as control variables for optimising the performance of the system. During the process, a power triangle effect was discovered to reveal the causal relationship between frequency, phase shift and power, and to provide insights into the control of dynamic wireless power transfer systems. The primary zero phase angle frequency was used as the basis for developing a phase-plane-based switching point control method for static and dynamic wireless power transfer based only on the primary side state variables without needing any information from the secondary side of the system. Specifically, an innovative voltage corrector was proposed to purposely reshape the control trajectory to match the control law and to reach the control target from both sides of the resonance frequencies, leading to the right control solutions without oscillation for given control radii.The proposed method did not only solve the three major problems related to the control of series-series wireless power transfer systems, i.e. frequency bifurcation, multiple solutions for one control radius and oscillation, but also ensured the system could achieve a high and efficient power transfer under dynamic operating conditions and in the meantime provide self-protection to the wireless power transfer systems

Full textThis thesis deals with the synchronization of dynamical systems. The synchronization considered is called master-slave, that is, the dynamical systems are connected in a unidirectional way. This configuration is of interest because it corresponds to an architecture encountered in secured communications of type one-to-one or one-to-many. A special attention is paid to self-synchronization. A behaviour that characterizes synchronization achieved with a simple master-slave coupling and so, without any external control. It is a central feature of self-synchronizing stream ciphers. The study of self-synchronization in the cryptographic context relies on control theory. An original connection between self-synchronization and encryption/decryption is provided. It is based on the flatness property of dynamical systems, a property borrowed from automatic control. It is shown that flat dynamical systems completly define the set of all self-synchronizing systems and thus, enlarge the existing structures of self-synchronizing stream ciphers. Flatness is first of all studied for the case of two nonlinear systems: switched linear systems and linear parameter-varying (LPV) systems. Flatness caracterization is based on the concept of nilpotent semigroups and an efficient algorithm is provided. A constructive approach for self-synchronizing master-slave structures is proposed. It relies on the construction of flat systems as well as on left and right invertibility also borrowed from control theory. Then, self-synchronization is studied in the Boolean context which is preferred in cryptography. Self-synchronization is caracterized through the notion of influence. Several matrix representations of Boolean functions are proposed. These representations are especially interesting for security analysis. A connection between self-synchronization and the eigenstructures of these matrices is established. Then, a graph oriented approach is provided. New self-synchronizing constructions are deduced and security elements are discussed. Eventually, the description of a realized FPGA based test plateform is provided

Full textThis PhD thesis is dedicated to the study of robust stability analysis and control synthesis for discrete time uncertain switching systems under arbitrary switching. Polytopic uncertainties are considered. We show that Lyapunov functions that depend on the uncertain parameter and that take into account the structure of the system may be used in order to reduce the conservatism related to uncertainty problems. Next, we consider the case of discrete time switched systems that are stabilized by a switched state feedback for which the switching signal may be temporary uncertain. Dwell time conditions for stability analysis of such systems are given. These results are usefull in the context of continuous time are stabilized via a computer when uncertainties occur on the sampling and actuation events. We present a new event based discrete-time model and we show that the stabilizability of this system can be achieved by finding a control for a switched polytopic system. The methodology is extended to the case of switched system

Full textAcute Myeloid Leukemia (AML) is a clonal hematopoietic disorder characterized by the accumulation of malignant hematopoietic progenitor cells with an impaired myeloid differentiation program. The molecular basis of AML is thought to be associated with the acquisition of at least two types of critical cooperating mutations occurring at the hematopoietic stem or committed progenitors level. Class I mutations, affecting tyrosine kinases receptors and key components of cellular signalling pathways, confer growth and proliferative advantages. They are associated with class II mutations, affecting transcription factors thus leading to impaired normal differentiation program. In this study, we were first interested in CHK1, a protein kinase involved in preserving genome integrity by playing a critical role at the intra-S and G2/M cell cycle checkpoint activated in DNA damage response. We have shown that activation of CHK1 was sustained in immature cell lines, leading to a more stringent G2/M checkpoint in response to DNA damage, thus impairing illegitimate entry into mitosis in presence of unrepaired DNA damage and participating in their resistance to genotoxic agents. In a second study, we have demonstrated an abnormal activation of the CHK1 kinase in a large panel of AML patient samples, associated with the presence of constitutive DNA damage in absence of genotoxic stress. Moreover, the level of CHK1 activation is significantly correlated with unfavourable cytogenetic samples, particularly with complex karyotype phenotype. CHK1 inhibition by the pharmacological inhibitor UCN-01 or by RNA interference was found to decrease the clonogenic capacity of the AML progenitors, and to induce a chemosensitisation to ara-C. In contrast, growth of normal hematopoietic progenitors, which do not display constitutive DNA damage, was not impaired by such treatment. Overall, all these results underline the dual role of CHK1 kinase in AML pathology in the chemoresistance of immature leukemic cells and in the establishment of the genomic instability observed in complex karyotype AML. These findings could have major pharmacologic consequences, because they open a therapeutic window for new compounds targeting the cell cycle checkpoint machinery in AML and more particularly in the worst prognostic group with complex karyotype
