Abstract: Aiming at the micro vibration caused by mass imbalance of high-speed magnetically suspended rotor, a novel electromagnetic force vibration compensation control method based on adaptive notch filter has been studied. Considering the influence of mass imbalance disturbance, the closed-loop control system model is established, and the internal relationship between mass imbalance and electromagnetic force disturbance is analysed. The simulation results show that the method can effectively suppress the influence of electromagnetic force induced by mass imbalance and reduce the micro vibration of the whole system.

Keywords: magnetically suspended rotor; mass imbalance; notch filter; vibration control; force compensation.
