有源电力滤波器常用控制策略的分析比较

针对有源电力滤波器(APF)的控制,将几种适用于有源滤波控制算法进行对比分析,简要介绍了比例积分控制、滞环控制、无差拍控制、三角波调制、单周控制、空间矢量控制、变结构控制及滑模控制、重复控制、预测控制、模糊控制等几种目前应用较为广泛的控制策略.在分析其工作原理的同时,指出各自的优缺点和应用范围,并对部分控制算法的发展方向进行了探讨性阐述.

Comparisons of several control strategy on active power filter

Considering the control of the active power filter(APF),the comparison and analysis of several control strategies on active power filter is proposed in this paper.Several novel control strategies widely used at present have been introduced briefly(PI control,hysteresis control,dead beat control,SPWM control,one-cycle control,space vector control,variable structure control and sliding mode control,repetitive control,predicted control,fuzzy control).Furthermore,their individual advantages and disadvantages,available scope,development orientation also have been indicated.
