Abstract

This paper discusses different regenerative braking control strategies of electric vehicle (EV), presents a novel H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> robust regenerative braking control strategy for electric vehicle. Research work is done under different conditions namely variable battery voltage and variable load rotational inertia, separately. A comparison between conventional PID control method and H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> robust control method is done when they are applied to the above mentioned conditions. Under the regenerative braking condition, simulations results show that H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> robust control has better performance than the traditional PID control both in steady-state tracking error and response speed and improve the drive range of electric vehicle.
