摘　　要：本文分析了重复控制技术与双环反馈控制技术的特点,取两者之长组成复合控制技术,双环反馈控制器居于控制系统内层,以改善系统的动态响应性。重复控制器居于控制系统外层,以减小负载等因素造成的谐波失真,提升静态稳定性。通过MATLAB仿真结果表明了复合控制策略具有良好地稳态性与动态性。The characteristics of repetitive control and dual-loop feedback control are presented in this paper. The two control strategies are incorporated as a hybrid control strategy： the repetitive controller serves as an outerlayer controller to eliminate the harmonic distortion and the dual-loop feedback controller serves as inner-layer controller to increase stability. The hybrid control strategy is simulated through MATLAB and the result shows that the hybrid control system has good static and dynamic characteristics.
