摘　　要：提出一种新的改进型重复控制策略,克服了传统重复控制器内模使用过多数据存储空间的缺点。详细分析新型控制器的模型,给出控制器优化设计方法。在设计中加入电流内环,通过电感电流反馈来降低输出滤波器的谐振峰值,增加系统的稳定性,简化了重复控制器的设计。与传统直接重复控制器相比,去除了North滤波器,弥补了North滤波器谷点设计不精确的缺点。A kind of novel improvement type repeated control strategy is put forward, weakness of the traditional repeated controller mold inside uses an excessive data saving space is overcomed. The model of new controller is analysed in detail,controller＇s optimal design method is given. Joining wreath inside of current in the design, using the current feedback of henrymeter to lower resonance voltage maximum value of output filter, the stability of system is increased, the design of repeated controller is simplified. Comparing with direct traditional repeated controller, it removes North filter, makes up the difference of North filter valley point is inaccuracy.
