Abstract

This paper presents an approach to research the active suspension system under LQG control strategy through the method of co-simulation using ADAMS and MATLAB. For this approach, the dynamic model of 1/2 automobile suspension system is created in the ADAMS, and then the LQG controller of suspension system is established by MATLAB, taking the vertical acceleration of the vehicle, pitch angular acceleration, dynamic displacements of wheels and dynamic deflections of automobile as performance indicators. The co-simulation results indicate that the LQG control active suspension can improve the ride performance and handling stability of automobile, and the method of co-simulation provides a new way for the dynamic simulation of automobile.
