Robust Sliding Model Control for Regenerative Braking of Electric Vehicle

A novel sliding mode control based on H_infin theory has been developed to meet the nonlinear control of regenerative braking of electric vehicle(EV). By combining the sliding phase and the hitting phase, the parameter of the sliding mode controller is designed by H_infin optimization procedure. In the scheme the sliding mode is ensured from the beginning of the response without the reaching problem and the traditional clustering is reduced. In addition, the gain matrix of the system guarantees the robust stability and disturbance rejection specification. Comparison is made between conventional PI control and the proposed scheme. Simulated results showed that the robustness and superior dynamic performance of the proposed control system
