H∞ Control Applied to Electric Torque Control for Regenerative Braking of an Electric Vehicle

Zhi-Feng Bai, Shu-Xin Li and Bing-Gang Cao
The state space model and the design of H∞ robust controller for regenerative braking of an EV(electric vehicle) driven by permanent magnet DC motor were presented. The controller was developed to make a good combination between regenerative braking and mechanical friction braking system and to minimize the effect of disturbance, such as the variation of initial speed and driving mode. The experimental results with different initial speed and driving modes show that energy saving and good combination between regenerative braking and mechanical friction braking are synchronously available by H∞ controller and the H∞ controller is prior to the traditional PID controller in both steady-state tracking error and response speed.
