Design of Linear-Nonlinear Cooperative Controller for Control Moment GyroscopePower Module

In this paper,the controller of Control Moment Gyroscope(CMG) power system is studied.The linear-nonlinear cooperative controller and circuit module is designed based on the analysis of linear controller and nonlinear controller. The nonlinear controller is used in the dynamic adjustment stage and the linear controller is used in the steady state stage. This scheme improves the dynamic performance of the power system and ensures the stability and reliability of the system. The simulation analysis of the robust controller is carried out and the module is built. The experiment verifies that the impulse is reduced by 45%, and the adjustment time is reduced by 58% when the state of the power module is switched by using the cooperative controller.And this proves that the cooperative controller can effectively improve the dynamic performance of the CMG power system.
