摘　　要：以自适应线性组合器为时变谐波检测器的模型,根据逆归最小=乘(RLS)自适应滤波算法较好的跟踪性能,使之应用于时变谐波的跟踪检测。仿真表明该方法比以往的基于最小均方(LMS)自适应滤波算法的谐波幅值和相位参数的测定具有更好的跟踪效果。Based on adaptive linear combiner (Adaline), a model for time-varying harmonic detection is established. Due to its excellent tracking performance, the recursive least squares (RLS) adaptive filter algorithm is good at time-varying harmonic's detection. Simulation shows that this method has better tracking result in harmonic's amplitude and angle parameters detection than the method based on least mean square (LMS) adaptive filter algorithm.
