针对三相三线制电路中的谐波补偿问题，采用模糊滑模控制方法设计了一种新型并联有源滤波器，成功降低了三相电路中电源电流的谐波电流含量。谐波电流检测方法采用p-q谐波电流检测方法，能快速、准确地检测出负载电流中的谐波分量。直流侧电压采用PI控制方法实现稳定控制。参考电流跟踪控制采用所设计的模糊滑模控制方法实现。Simulink仿真结果显示，与传统的滞环比较控制方法相比，所设计的新型模糊滑模控制方法能够有效地降低跟踪误差，提高有源滤波器的谐波补偿效果。

This paper designs a shunt active power filter with the novel fuzzy sliding mode control method to solve the harmonic compensating problem in three-phase three-wire grid and reduces the harmonic distortion of the supply current successfully. The p-q harmonic detection method is applied and the harmonic component in load currents can be extracted quickly and exactly. The PI control technique is used to control the stability of capacitor voltage in DC side. The designed fuzzy sliding mode control method is applied in the reference current control. Simulation results reveal, compared to the hysteresis controller, the designed fuzzy sliding mode control method can reduce tracking error obviously and improve the harmonic compensation effect of active power filter.
