When the active-passive hybrid magnetically suspended Control Moment Gyro (CMG) rotor rotates, synchronous vibrations are caused. To achieve active vibration control, the coupling characteristic along the radial deflection angles between passive and active bearings was analyzed. Based on this, the composite feedforward compensation method for active vibration control of active-passive hybrid magnetically suspended rotor was proposed. The impact of coupling magnetic forces between active and passive bearings was taken into account in the process of lead feedforward compensation for displacement stiffness forces. And the coupling current stiffness forces were compensated between the radial degrees. Simulation results show that, the proposed method can reduce the synchronous bearing forces to 9.3% of that without compensating the couplings.
