摘 要：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 carded 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.
