Parameters Analysis and Design of Repetitive Learning Control Strategy for Shunt Active Filter

为了消除谐波抑制过程中重复学习控制器不稳定因素对控制品质的影响,论文以LCL滤波器的有源电力滤波器系统稳定性和补偿性能作为切入点,理论分析了重复学习控制器的参数选取范围,同时仿真结果验证了该理论的正确性和有效性。

In order to eliminate the influence of some instabilities with repetitive learning controller to the control quality in the process of harmonic restraining. The parameters choosing range of repetitive learning controller is analyzed theoretically based on the stability and compensation effect of Active Power Filter （APF） system with LCL filter. The simulation results verify the correctness and effectiveness of the theory.
