Abstract

This paper aims to provide a robust control system for an induction motor (IM) used in electric vehicle (EV). A digital RST controller is designed to reduce response time without overshoot speed. High-dynamic performance is obtained by using the indirect stator-flux-oriented control (ISFOC) and the space vector pulse width modulation (SVPWM). In this paper, a three level neutral-point-clamped (NPC) has been used for electric vehicle applications. Multilevel converters can generate the output voltages with very low distortion and can reduce the dv/dt stresses; moreover, electromagnetic compatibility (EMC) problems can be reduced. The simulation results show the robustness and effectiveness of the proposed approaches.
