摘要

直流侧电压的稳定控制是保证有源电力滤波器（APF）性能的关键。文中基于APF直接功率控制系统，给出直流侧电压功率控制模型，提出采用分数阶比例-积分（FO-PIλ）控制器进行直流侧电压稳定控制，采用频域方法设计FO-PIλ控制器，并用来调节直流侧电压的大小和波动，以减少对APF的功率损耗和补偿性能的影响。仿真分析表明:基于FO-PIλ控制器的APF直流侧电压控制具有良好的动态性能和更强的鲁棒性;在负载扰动和电压闪变的情况下直流侧电压仍然稳定，能够快速精确地稳定在给定值;新的控制方案优于传统使用比例-积分（PI）控制的方案。

Abstract

DC voltage control is the key to guaranteeing the performance of active power filter（APF）.A fractional-order PIλ（FO-PIλ）controller is proposed to realize the stability control of DC voltage of APF using the DC voltage power model in the direct power control（DPC）system.The FO-PIλ controller is designed with the frequency-domain method，and is used to regulate the value and fluctuation of the DC voltage to reduce the bad influence on the power loss and compensation performance of APF.The simulation results show that the DPC system of APF based on the FO-PIλ controller has good dynamic and robust performance，and the DC voltage remains stable during impulse-voltage and load-change.The DC voltage stabilizes at the given value quickly and accurately.The new control strategy is better than that using the traditional PI controller.
