摘要
Abstract
Since the fixed-step algorithm has a limitation that it cannot keep a balance between steady accuracy and ra⁃pidity,and the existing variable-step algorithm has the disadvantages of heavy computation load and numerous un⁃known parameters,a new automatic adjustment iterative algorithm according to the error is deduced based on the theory of mean square error(MSE),and it is applied to the harmonic detection of active power filter(APF). The proposed algo⁃rithm has the advantage of less computation load,and based on the fastest decline of MSE,it adopts a large step when the error is bigger to ensure its rapidity,and uses a small step when the error is smaller to guarantee the steady accura⁃cy. The rapidity and accuracy of the proposed algorithm,and the feasibility of its application to the harmonic detection of APF,are verified by Matlab simulation and experiment.关键词
