针对实际应用给出了重复控制器内模、补偿器以及周期延迟环节的优化设计方法，推导出了重复控制器的稳定性判断条件和收敛指数。基于3 kVA逆变器硬件和控制参数设计了重复控制器，给出了重复控制器各关键参数的设计过程，并进一步基于重复控制器稳定性判断条件对设计结果进行了稳定性验证。利用Matlab软件对设计结果进行了验证，仿真结果表明在逆变器控制中添加重复控制器后，能明显降低逆变器带非线性负载时输出电压的总谐波失真度值。

fAccording to the demand of practice application,the optimized design methods of internal model,compensator and cycle delay unit of repetitive controller are also given,and the stability judgement conditions and constringency speed of the proposed repetitive controller are deduced for design validation. This proposed repetitive controller designed for inverter was rea-lized based on 3kVA inverter and control parameters. The design procedure of each important parameter for repetitive controller is given. The stability of the designed repetitive controller is validated on the basis of the stability judgement conditions of the re-petitive controller. The simulation results show that the inverter with the proposed repetitive controller can achieve low total har-monic distortion under nonlinear load.
