摘　　要：为了进一步提高有源电力滤波器(APF)的补偿性能,本文提出了一种将输入/输出反馈线性化与基于电压空间矢量的双滞环脉宽调制相结合的APF复合控制方法。通过反馈线性化理论,将APF在d-q坐标系下模型解耦为两个独立的电流环,构成两个电流内环和一个电压外环的控制结构。提出一种采用旋转坐标系下主电路开关函数控制量作为原系统模型的输入变量,来确定主电路交流侧参考电压矢量的方法。仿真结果表明该复合控制方法实现了APF系统模型的线性化和补偿电流d、q分量的解耦,系统在稳态和负载突变的情况下都具有良好的补偿特性。In order to improve the performance of active power filter （APF）, the paper proposes a novel compound control method which combines input/output exact feedback＇ linearization with double hysteresis control for shunt APF. By the application of feedback linearization theory, the model of APF under the synchronous orthogonal ＇dq＇ frame is decoupled into two separate current loops, namely the two current inner loops and the DC voltage outer loop. A new method to calculate the reference voltage vector of the double hysteresis system through the control variables of main circuit＇s switch function under the synchronous orthogonal ＇dq＇ frame is also proposed. Simulation results show that the proposed compound control method realizes APF model linearization, compensation currents decoupling and good compensation performance in both steady and dynamic state.
