Rotor Vibration Control of Active Magnetic Bearing System Using Adaptive Forced Balancing Method


Article Preview

The adaptive forced balancing (AFB) method was used to estimate and eliminate the rotor vibration with unknown amplitudes and frequencies in active magnetic bearing (AMB) feedback control systems. Firstly, the rotor vibration producing mechanisms of AMB were analyzed. Then, the AFB under the assumption of unknown rotational frequency and amplitude are designed. Finally the simulation results show that the AFB method proposed in this paper makes it possible to completely reject unknown sinusoidal disturbance in a closed loop control system
