Abstract :
The exact stationary response of the suspension vehicle system under the random road excitation is deduced based on the stochastic averaging method. Then, the control law is assumed to be velocity feedback control and the unknown control gains are determined by minimizing the modal performance indices. A quarter-car model is taken as example to illustrate the proposal method and the numerical results are confirmed by using the numerical simulation.
