Trajectory tracking control of autonomous vehicle is a prerequisite to achieve vehicle intelligence. The suspension system performance will greatly affect the path tracking error. This article designed a new type of magneto-rheological damper (MR damper)
and the dynamic performance test of the MR damper was carried out on the test platform. A semi-active suspension dynamic model based on the MR damper was established according to the test performance. Then a nonlinear model predictive controller was designed
based on the nonlinear vehicle dynamic model of 8-degree of freedom (8-DOF) combining with semi-active suspension model
and the simulation result was verified under MATLAB/Simulink environment. The result is compared with the controller with passive suspension control. It is concluded from the result that
adding semi-active suspension control can improve the tracking accuracy and the handling performance in vehicle path tracking.
