摘　　要：将三维空间矢量概念与滑模变结构控制技术相结合,并将其应用在三相4线制4桥臂有源电力滤波器中。为了使三相电源电流为正弦波的控制目标,首先建立有源电力滤波器在dq0坐标系中的统一数学模型,通过等效控制的方法推导出其滑模变结构控制方法,并对滑动模态的存在性、可达性和稳定性进行了分析。最后在Matlab/Sinmulink环境下对所提控制策略进行了仿真研究,仿真结果表明所提控制策略可以有效地抑制谐波,并且具有很好的通用性。A novel control strategy for the three phase four wire shunt active power filter by using the three-dimension space vector concept and sliding mode control technology was put forward.For the sake of optimal controlgoal to enable the source being sinusoidal,established a unified mathematical mode for APF in the synchronous dq0 frame,then the sliding mode control（SMC）strategy was deduced by the equivalent control method. Analysis for theexistence,accessibility and stability of sliding mode were performed. The simulation in Matlab/Sinmulink is providedto verify the proposed control strategy.
