Experimental Research on H8 Control for Regenerative Braking of Electric Vehicle

A novel H_∞ robust regenerative braking control strategy for electric vehicle (EV) is presented after different regenerative braking control strategies are discussed in this paper. Research work is done under different conditions namely variable battery voltage and variable load rotational inertia, separately. A comparison between conventional PID control and H_∞ robust control is done when they are applied to the above mentioned conditions. Experimental results show that H_∞ robust control has better performance than the traditional PID control both in steady-state tracking error and response speed.
