In this thesis, using stochastic linear optimal control theory and PID control strategy for the control process of sus-pension system, the model of suspension system and the model of road surface are established.Dynamic displacement of the tire, suspension travel and body acceleration are applied as the control objectives.Through simulation analysis, we find that the optimal active suspension significantly reduces the vertical vibration acceleration of the car body, thus increases riding comfort ability of vehicles.
