Analysis on the stability and anti-interference performance of EHPS system in pure electric bus

This paper studies the stability and anti-interference performance of the EHPS system of the pure electric bus, analyzes the influence of the disturbance of road excitation and the sensor's noise measurement on system performance, combines the traditional PD control algorithm and the H∞ control theory and applies it to the research of steering control system and design of the controller. The computer simulation results suggest that EHPS system of pure electric bus designed boasts good stability, and can effectively inhibit the influence of the disturbance of high-frequency road excitation and the measurement noise of the torque sensor on the system.
