摘 要：An automobile power-train active mount system with a piezoelectric stack actuator is introduced.The influence caused by power-train to the body of the car is analyzed by means of parameter self-tuning fuzzy PID control,on which the simulating results are based.It turns out that this control scheme can restrain the influence better caused by power-train to the body of the car.
