摘　　要：在分析了传统重复控制方法优缺点的基础上,提出了一种基于模糊自整定PI控制和重复控制相结合的新型单相SPWM逆变电源控制方案,利用模糊自整定PI控制改善了系统的动态特性,利用重复控制改善了系统的稳态特性。仿真结果表明,该控制方案使正弦波逆变电源系统获得了良好的稳态和动态性能。In this paper, a novel control strategy of adaptive fuzzy-PI control and repetitive control is presented based on detailed analysis the merits and demerits of the repetitive control. The dynamic state characteristics of the system are improved by using adaptive fuzzy-PI control, and the steady state characteristics of the system are improved by using repetitive control. The simulation results show the system achieves good dynamic and static performance.
