摘要：
The working performance of the active power filter is dependent on harmonic current detection. Based on adaptive noise canceling technology, this paper improved the classic LMS algorithm ant got a fuzzy variable step-size LMS algorithm of harmonic current detection which uses the average estimation of error signal to control the updating of step-size by fuzzy inference. The algorithm has a fast response while ensuring high precision. The simulation results verify the effectiveness of this algorithm.
