| Abstract: | Setting up the dynamic equation of one quarter vehicle model, based on the LQG and PID control theory, with the aid of matlab/simulink software, the simulation model is obtained. Compared with the passive suspension system, the body acceleration, suspension displacement and the tire travel is analyzed. The results indicate that the LQG and PID controller is effective in improving the vibration comfort of the vehicle. |
