摘　　要：对控制力矩陀螺电源的控制器进行研究,基于对线性控制器及非线性控制器的分析,设计了线性非线性协同控制器并搭建硬件模型,在电源系统动态调整阶段采用非线性控制器,在稳态阶段采用线性控制器。该方案较单一线性控制器提升了电源系统的动态性能,并保证了系统的稳定性及可靠性。对该鲁棒控制器进行了仿真分析并搭建实物,通过实验验证了相较线性控制器,使用协同控制器的电源模块在控制状态切换时,下冲量与调节时间分别减少了45%及58%,证明了该协同控制器能够有效提升CMG电源系统的动态性能。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.
