Active fast vibration control of rotating machinery via a novel electromagnetic actuator
This paper presents an active fast vibration control (AFVC) strategy applicable to rotating machinery. The actuator utilized is a novel active magnetic bearing that could achieve the integration with a hole‐pattern seal. The control algorithm leading to an electromagnetic force with an optimal combination of phase and magnitude under a certain speed is based on the principle of feedforward compensation and self‐optimization. The AFVC algorithm is implemented in a real compressor rotor system model and experimentally demonstrated on two test rigs of different scales. There is at least a 70% reduction in vibrations within 1 s over the case with no control. Excellent vibration control effects can be maintained even when the rotating speed is fluctuating. Furthermore, the proposed method could be free from elaborate system modeling and vibration phase extraction in practice, dramatically simplifying the control system design.
