N2 - To reject the influence of gyroscopic effects on system stability and to attenuate the imbalance vibration for active magnetic bearing (AMB) of a magnetically suspended control moment gyro (MSCMG), this paper proposes a controller composed of a complex exponential function feedback and a clean current approach. The AMB is modeled and its dynamic analysis is performed, the complex exponential function feedback can provide proper phase adjustment and effectively suppress the nutation and the precession of the gyroscopic effects, notch filter is adopted to clean the synchronous current and to compensate the imbalance vibration. The stability and parameters of the AMB are analyzed and designed by using the root locus method. Both simulation and experimental results indicate the good effectiveness of the presented approach.
