The grey theory was applied to set up a model of grey PID control on the semi-active suspension with magnetorheological damper, and the controller design method was discussed. In this dissertation, an automotive vibration model of 1/4 body with 2 degree-of-freedom is created, which is based on the automotive dynamics theory. At the same time considering the great influence of the road disturbance on the suspension, the mathematical model of road surface irregularity with the kind of white noise is established. And the simulating input of road surface utilizes the C-class road. The programming steps under MATLAB platform are described. It provides a new method for the semi-active suspension contro1.
