An optimal vibration control strategy of AMB-flexible rotor syxstem

Flexible rotor systems supported by AMBs demonstrate sophisticated and vibration performance due to the excitation of unbalance disturbance and flexible modes. The displacement of rotor and control current under different rotating speed and control force is calculated. An compensation strategy of parameter variation controller to optimize the vibration suppression is designed considering all rotor nodes displacement and control current. The controller parameter is selected under different speed region and examined through simulation.
