Optimisation des stratégies de contrôle-commande d'un ensemble convertisseur en pont H-machine électrique à l'aide d'un système de prototypage rapide dSPACE pour application de véhicule électrique

Abstract : The laboratory of new technologies (LTN) is about to get an evolutive test bench in order to reproduce in lab environment the constraint applied to a set of a 3-H bridge inverter and a PMSM intended to electric vehicle (EV) applications. One of the objectives of the LTN research works aims to improve electric powertrain performances by minimizing both the switching losses and the additional ones due to a zerosequence current. Furthermore, the structure should be reconfigurable in case of fault. This paper presents and compares the different strategies of control of all H-bridge inverter and induction motor by Space Vector PWM (SVPWM). This comparative study has been conducted following two control drive requirements: minimizing zero-sequence current and its ripple, and optimizing switching losses. Thus, the choice of a method of SVPWM is justified. The scalar control of induction motor is also the subject of this manuscript. Indeed, the paper recalls the electric model of the induction motor and explains the principle of scalar control. On a dSPACE controller board, a real-time implementation of a method of SVPWM strategies and control laws of the induction motor (current loops) was conducted to experimentally validate the preliminary results of simulations.
