摘要
分析了三相并联型有源电力滤波器(APF)原理和电流控制数学模型。接着将重复控制器嵌入到有源电力滤波器(APF)中,实现PI控制和重复控制的双闭环电流控制。同时讨论了重复控制的稳定性和稳态误差,分析了重复控制器的参数设计。最后在一台20kVA并联型有源电力滤波器样机上验证了该方法的使用性和有效性。
The principle of active power filter （APF） and the mathematical model of current control were analyzed. The repetitive controller was embedded in an active power filter system and the double closed-loop current control was realized with PI control and repetitive control. Also the stability and steady-state error of APF system with repetitive controller was discussed and the design of repetitive controller was analyzed. Experimental results verified the efficiency and feasibility in a 20kVA APF prototype.
