摘要：

To restrain disturbances produced by parameter variations and external disturbances in axial magnetic bearing in the application of single-gimbal magnetically suspended control moment gyro (SGMSCMG), a disturbance observer control method is proposed, which integrated H controller and disturbance observer. This method considers parameter variations of the axial magnetic bearing and the effect of gimbals on axial magnetic bearing. Consequently, the state space equation is changed to include the disturbances. Then the robust controller is designed, which includes the disturbance observer design and robust H controller design. The stability analysis is given for the proposed controller. Simulation and experiment results on the SGMSCMG verified the correctness of the proposed method.
