Robust nonlinear control applied to traction control of electric vehicles

摘要

In this paper, a robust nonlinear control strategy based on sliding mode control algorithm is applied to traction control for an electric vehicle (EV) with four separate wheel drives. The proposed algorithm is implemented in terms of a hierarchical architecture, which incorporates all new known vehicle systems ABS (Anti-lock Brake System), ASR (Anti Slip Regulation), ESP (Electronic Stability Program). Simulation results demonstrate the satisfactory robust performance of the proposed control algorithm.
