| Abstract: | The decoupling and active control of self-excited vibration in a 2 degree of freedom dry-friction sys tem are investigated.Adopting the averaging method,the pure slip type self-excited vibration is analyzed.The decoupling law is designed by the theory of nonlinear differential geometry method,and the sliding mode variable structure control of the decoupled linear subsystem is used to stabilize the flutter.The influence of the controller and the system parameters are analyzed.The simulation result shows that the sliding mode variable structure control method is an effective way in control of the frictional flutter. |
