To improve the vehicle comfort, Magnetorheological damper is installed on the vehicle suspension system. So the system with hysteretic nonlinearity is a typical nonlinear system. First, the behavior of system under the periodic excitation force is analyzed, and the possibility of chaos is proved in the paper. Then, with piecewise-quadric function employed, the nonlinear feedback controller can be used to control the chaos. At the same time, Melnikov’s method is used to gain coefficient of controller. Numerical simulation shows that this method can the effectively guide chaotic motions toward regular motions. This control method is quite simple and effective without affecting the system properties. The results may supply theoretical bases for analysis and optimal design of vehicle suspension systems.
