Abstract :
The electrification of transportation is one of the relevant solutions to reduce greenhouse gas emissions. Indeed, new European standards impose increasingly restrictive limits on C02 emissions per km. This context is an essential industrial issue for automobile manufacturers. Therefore, the industries are moving towards electric vehicles (EVs) in which an electric powertrain unit is present. This unit consists of an electrical machine powered by a static power electronic converter connected to an electrical energy source and storage. Different topologies have been studied for more than two decades for electric traction, and several solutions have been marketed. As a result, these products are increasingly light, reliable, and efficient while respecting the constraints of the automobile manufacturers on the costs.
Recently, permanent magnet assisted (PMa)-synchronous reluctance motors (SynRM) have been considered a rare-earth-free machine possible alternative motor drive for high- performance applications suitable for EV powertrain units. However, in order to have an efficient motor drive, performing three steps in the design of the overall drive is not inevitable. These steps are design optimization of the motor, identifying the motor parameter, and implementing an advanced control system to ensure optimum operation.
Therefore, this dissertation deal with high-performance nonlinear control of PMa-SynRM to find out the limitation of exiting nonlinear control system.
The differential flatness-based control is first developed for the PMa-SynRM drive system. As it is a model-based control, the system performance relies on system model parameters, i.e., resistance, inertia, and external torque disturbance. Next step, model-free control is presented to be used in the control of both the SPMSM and PMa-SynRM. Finally, this thesis has achieved the main objective of finding out the high-performance nonlinear control of PMa-SynRM. Using a prototype PMa-SynRM drive as a test bench provided by GREEN Lab. at Université de Loraine, this paper gives an exhaustive description of an MFC’s design procedure applied to the combined control of the motor speed and current. After a brief introduction of the MPC fundamentals, the design is illustrated in detail, giving a step-by-step discussion of the main critical points and the hints for their successful handling. Suggestions for extending the design to different drive controllers are also included. Simulations and numerous experimental results highlight the promising features and characteristics of MFC applied to PMSM drives. As the last contribution, the MFC potentials pointed out in this dissertation should stimulate further exploration and study on this type of controller to achieve the familiarity required to transfer the results to practical applications.
