Feedback loops and the actuator delay is to have a bit rate of negative feedback on the structure of the main reasons for high-frequency self-excited vibration. Under certain conditions, as long as the feedback gain is large enough, high self-excited vibration occurs. This self-excited vibration generated critical feedback gain is inversely proportional to the critical delay. References 1 Chung-Gu right horse buckle root, Chen Weidong. Active vibration control.
