摘要
主要研究了基于最小均方算法的谐波电流检测的新方法,在分析最速下降法的基础上,采用误差信号平方的梯度作为向量梯度进行性能函数的描述,进而引入了最小均方算法的数学模型,并引入了谐波电流检测模型,将最小均方算法应用到谐波电流检测方面.为表示本文算法性能的优越性,将递归最小二乘算法作为对比应用到谐波电流检测方面,最后利用MATLAB软件对两个算法进行编程仿真,通过对比分析验证本文算法的性能.
A new method of harmonic current detection based on the least mean square algorithm is mainly studied.On the basis of analyzing the fastest descent method,the gradient of the square of the error signal is used as the vector gradient to describe the performance function.Then the mathemati-cal model of the least mean square algorithm is introduced,and the harmonic current detection model is introduced as well.The square algorithm is applied to the harmonic current detection.In order to show the superiority of the algorithm performance,the recursive least square algorithm is used as the contrast to the harmonic current detection.Finally,the two algorithms are programmed and simula-ted by MATLAB software,and the performance of this method is verified by comparison and analy-sis.
