Abstract: The active vibration control of the flexible cantilever beam with PZT actuators was studied, and the principle and the method of theactive vibration control were analyzed. Using the independent mode space controlmethod, the active control experiment on the first-order and second-order mode vibration of the flexible cantilever beam was performed. The experiment results show that the damping of the flexible cantilever beam is increased significantly by introducing the active vibration control method, and the excellent vibration control effect is obtained.
