单相并联型 APF 改进双环控制技术仿真研究

摘要

对单相并联型 APF 双环控制技术的控制器做出了改进,提出 PI＋重复的改进双环控制技术,阐述重复控制的思想,并对复合控制器进行设计,MATLAB 仿真表明,改进技术能够改善其在高频中补偿能力不足的问题,提高了电流环的跟踪能力,达到很好的补偿效果。%This paper has made the improvement to the control technology of the controller for the single-phase shunt APF,put forward the improved control technology of PI with repetition,expounded the re-petitive control thought,and designed the compound controller.The MATLAB simulation results show that the improved technology can improve the insufficient capacity in high frequency compensation,im-prove the current loop tracking ability,and achieve good compensation effect.
