Abstract
Active suspension system is a hot issue in the recent research of automotive industry, which is to generate active force to suppress the variation of the vehicle and improve safety and comfort for the passengers. By observing the dynamics of the vehicle, the controller output forces through linear actuators. Integral sliding mode control is applied here to calculate the output forces and then reject the disturbance. In this paper, an accurate nonlinear active suspension system model is developed first; decoupling of the sprung mass subsystem is investigated hereafter to isolate the dependence of the variables, then integral sliding mode control is used to reject the disturbance and reach the referenced surface for each subsystem. PID control, as a conventional control method, is compared here with the integral sliding mode control. The simulation results show the effectiveness of the proposed control method.
