Abstract

The vehicle dynamics models which have integrated electric power steering (EPS) and active suspension system (ASS) were built, the integrated LQG (Linear-Quadratic Gaussian) controller which adopts centralized structure was designed, computer simulations were carried out with the MATLAB/Simulink software. The simulation results showed that the LQG controller could not only apparently filter sensor measurement noise influencing the integrated systems, but also effectively improve vehicle handing stability and steering portability.
