摘要
利用有源电力滤波器装置(APF)的非线性特性,提出一种基于欧拉-拉格朗日(EL)模型的三相并联型APF的无源性非线性控制方法。为了确保APF直流侧平均电压稳定在设定值,提高APF的谐波补偿精度,采用基于非线性PI控制的APF直流侧电压外环控制。Matlab仿真实验证明此方法控制的APF具有很好的谐波补偿效果,在负载突变的情况下具有很好的动态响应速度。
A passivity-based control method for three phase parallel APF based on Euler-Lagrangian model （Euler-Lagrange, EL） is proposed based on non-linear characteristics of the active power filter device （Active Power Filter, APF）. In order to ensure that the DC side average voltage of APF stability in setting value, the accuracy of APF harmonic compensation is increased, which based on nonlinear PI control for APF DC side voltage. Simulation experiments, based on Matlab, show that the APF controller based on the proposed method has a good harmonic compensation performance and also has a good dynamic response in load mutations.
