| 摘 要： | 提出一种新的基于LMS算法自适应滤波器的有源电力滤波器(APF)参考电流的预测方法，针对传统LMS算法的缺陷(如收敛速度慢、对非平稳输入信号的适应性差等)作了3点改进，这些改进措施可有效提高自适应滤波器的综合性能．仿真与实验结果证明，采用该方法可有效减小延时对APF补偿效果的影响．

| Abstract: | A new method based on adaptive filter to predict the reference current of active power filter is presented. To solve the (drawbacks) of the traditional LMS algorithm, such as slow convergence and poor adaptability to the non-smooth (input,) three modifying measures are proposed, which effectively improves the comprehensive (performance) of the adaptive filter. Simulation and experimental results show the effect of the proposed method to (alleviate) the (detrimental) (influence) of time delay inherent in the digital control system on the compensation effect of APF. |
