High-Stability and Fast-Response Twisting Motion Control for the Magnetically Suspended Rotor System in a Control Moment Gyro

To effectively improve the stability and dynamic performance of the twisting motion of the magnetically suspended rotor in a control moment gyro, a high-stability and fast-response twisting motion control strategy named as dynamic feedback–feedforward control is proposed in this paper. This method is oriented to the feedforward control strategy and the dynamic feedback signals are employed to determine the current feedforward values. The common issues caused by twisting motion can be effectively resolved by the proposed method. To verify the feasibility and superiority of this control method, comparative simulations and experiments between the traditional method and the proposed one are carried out.
