A Robust Nonlinear Control Based on SMC Approach for Doubly-Fed Induction Motor Drives Used in Electric Vehicles

This paper presents an improved sliding mode control strategy of an electric vehicle propulsion system based on a Doubly-Fed Induction Machine (DFIM). The aim of this article is to develop the model of this control technique of DFIM applied to electrical system traction and in order to prove its robustness against parameter variations. To monitor the power exchanges in the rotor and stator windings, a control strategy based on the classical power distribution method is presented. The performance of the proposed approach is investigated and results are approved by simulation using Matlab/Simulink environment.
