【Abstract】 The PID,LQR and LMS control methods,with the optimized parameters of the three methods,were used to perform the simulate experiment of active vibration control of the aircraft,which used Macro Fiber Composites( MFC) as control device. It was used to validate the feasibility of the active vibrate from simulate experiment. Come to the conclusion that the amplitude response from the simulate experiment has been suppressed well,and the control effect of LMS is better and the convergence time of PID is shorter.更多还原
