Experiment of H<sub>∞</sub> Driving Control System for Electric Vehicle

Abstract

This paper discusses different drive control methods of electric vehicle (EV), presents the design of H∞ robust controller for driving control, with the consideration of protecting the battery. Research work is done under different conditions namely variable battery voltage and variable load rotational inertia separately. Experiments show that the H∞ robust controller has better performance than the PID controller in both steady-state tracking error and response speed. Moreover, the H∞ robust controller can improve the drive range of electric vehicle.
