摘要：
Aiming at the semi-active suspension system with the CDC shock absorber, AMESim software is used to model the CDC adjustable dampmg shock absorber, and the dynamics of the two-degree-of-freedom semi-active suspension are analyzed. A genehc algonthm IS proposed to improve fuzzy rules. The method to control the CDC shock absorber can adjust the opening of the flow valve port, and the LQG control strategy is presented to obtain the optimal control force and achieve control of the damping force. Finally, some co-simulation is carried out by AMESim and MATLAB/Simulink. The results show that the LQG-fuzzy control using the genetic algorithm to improve fuzzy rules can significantly reduce the vehicle body's acceleration, and the suspension s dynamic deflection IS also reduced. It Improves the smoothness of the vehicle.
