摘　　要：为改善基于重复控制方式的三电平APF动态性能欠佳的不足,采用重复控制+滞后1拍PI控制的复合电流跟踪控制方式。为了进一步提高控制器性能,采用改进的蝙蝠算法对控制器参数进行优化,给出了参数优化结果。分别对传统PI控制与优化后的复合控制进行了Matlab/Simulink仿真实验。结果表明,复合控制方式静态与动态性能更好,能够更加有效抑制电网谐波,达到了预期目标。In order to improve the dynamic performance of tri-level active power filte(r APF)based on repetitive control,a compound current tracking control method combining repetitive control and one-beat lag PI control was used.For further improving the performance of the controller,the parameters of the controller were optimized by the improved bat algorithm,and the exact values of the parameters of the controller were achieved.Though the Matlab/Simulink simulation experiment of the traditional PI control method and the optimized compound control,the results demonstrate that the proposed method has better static and dynamic performance,and can suppress grid harmonic more effectively,and reach the desired goals.
