N2 - The resonance of turbine mode vibration and rotor rotation frequency is an obstruction to the stability improvement of a magnetic bearing supported molecular pump. The paper explores a generalized notch filter design method for suppression of the modal vibration of asymmetric rotor systems in magnetic levitation molecular pump. First, using complex coefficient method and filter cross-feedback control for nutation suppression, an equivalent single-input-single-output (SISO) model of the AMB-rotor system can be converted from the coupled multi-input-multi-output (MIMO) model. Then the generalized notch filter is designed by adding series correction procedures on traditional filters, which aims at providing adequate damping for the vibration modes, and avoiding possible decrease of system performance and instability of the AMB-rotor system caused by phase lag. Finally, simulation results show the proposed method is verified to have a great performance for suppression of vibration modes and improvement of stability using double-frequency bode diagram method.
