| Abstract: | A 2-degree-of-freedoms 1/4 body equations of vehicle active suspension was established.Based on the linear optimal theory,a LQG（linear Quadratic Gaussian）controller of automobile active suspension which is used for simulation with the aid of Matlab/simulink software was desighed.It showed that the suspension with the LQG controller could effectively improve vehicle’s riding performances. |
