Project #1:Development of a sizing algorithm for the modular mutlilevel converter (MMC). From the specification of an operating point in terms of DC-AC power transfer, the algorithm computes the parameters of the MMC.Development and Improvement of the computation time of real-time optimization control methods for the active capacitor balancing of the MMC. As a result, it enhances the scalability of the control method to the number of submodules (SMs) by lowering the computation time.Projet #2:Development of an offline algorithm to optimize the guidance trajectory of an electromechanical powertrain in a {speed, acceleration} plane while being compliant with the system's constraints and saturations.Development, implementation and testing of the control law on the real powertrain using Matlab-Simulink and dSPACE.

My research addresses Control Allocation Methods for Multilevel Converters. This work is done in the CODIASE (Control and Diagnosis of Electrical Systems) research team at the LAPLACE laboratory in Toulouse, FranceStrong results obtained with this research project:1) Development of new models of electrical polyphase systems with any number of phases. The models obtained have constant complexity and are independent of the number of phases.2) Development of control allocation methods for converters having a large number of switches: taking advantage of the multiplicity of switches in multilevel structures.3) Design of new real-time optimization control architectures for redundant systems, improving performances.4) Development of new control algorithms for currents in an electrical polyphase system with any number of phases. Neither the code of the algorithm, nor its real-time computation time changes as the number of phases increases.Development and Simulation: Matlab, Simulink, PLECS, Opal-RT (Hardware-In-the-Loop testing) Show less

This project was initiated by ArianeGroup and the call for tenders was addressed to the entire promotion of my specialty in engineering school. A set of specifications was given to us at the beginning of our last year of engineering studies and we had a semester to design the requested deliverables in parallel with our lectures. The objective of this project was to propose a design of a mechatronic system allowing, from an energy source embedded in a rocket, aerodynamic control surfaces to follow a mission profile imposed by the specifications while undergoing the constraints of the aerospace environment. This project was entirely managed by students, although we had some interventions from an experienced engineer to guide us in our approach. My work has mainly focused on the following points: - Understanding of the specifications and translation in terms of physical quantities over the entire mission profile - Pre-sizing at the 1st order of the system in order to guide the choice of the mechatronic system architecture - Modelling of the system and the constraints imposed by the specifications in the form of potential/flow diagrams - More detailed modelling of the electrical, mechanical and thermal behaviour of the various system components once the final architecture has been chosen (EMA type) - Optimization of the sizing of the chosen architecture in order to minimize the mass of the global system - Design of the system control to meet the specifications in terms of dynamics - Optimization of system control in order to minimize the mass of the overall system - Implementation of a Matlab application to check the various points of the specifications - Use of Matlab, Simulink and Simscape during the different phases of the project Development and Simulation: Matlab, Simulink, FEMM Show less
