N2 - Modal vibration affects seriously the stability improvement of AMB rotor system of MSCMG, even inducing a destructive crash. The vibration will be excited when the rotor rotation speed approaches the modal frequency. Besides, the modal frequency changes with rotation speed and working condition, which makes control issues complicated and difficult. This paper advances a modal vibration reduction approach with adaptive frequency estimation algorithm. And the model of AMB control system is established. An adaptive frequency estimator is designed to track the changing modal signal. Then, a negative feedback loop of notch filter at the modal frequency is added to control structure to reduce vibration. Finally, simulation proves the reduction effect of the proposed approach.
