摘要:

对现有用于三相三线制有源电力滤波器的比例+重复控制复合控制策略进行比较分析;并对其中的比例+重复控制串联复合控制策略提出两种改进方法,使其较于单重复控制具有更快的响应速度和更高的跟踪精度。通过理论分析、MATLAB仿真和样机试验,验证了控制策略的正确性和有效性。

关键词: 有源电力滤波器, 电流环控制, 比例+重复控制复合控制, 固有周期延迟

Abstract:

Three kinds of existing proportional + repetitive control composite control strategies for three-phase three wire active power filter are compared and analyzed,and two improved methods are proposed for the proportional + repetitive control in series composite control strategy,so that it has faster response speed and higher tracking accuracy than single repetitive control.The correctness and effectiveness of the control strategy are verified by theoretical analysis,MATLAB simulation and prototype test.

Key words: active power filter (APF), current loop control, proportional + repetitive control composite control, natural period delay
