Fisher
说明: 使用Fisher 现行判别函数对给定的样本进行训练,对于两类,Fisher线性判别函数很好做,就是 w = Sw (m1 - m2), 其中:Sw为总类内离散度矩阵, m1, m2, 为两个模式类的均值(Fisher discriminant function using the current sample of a given training for two, Fisher linear discriminant function is well done, that is, w = Sw ' (m1- m2), where: Sw of the total within-class scatter matrices, m1, m2, the mean value for the two pattern class)

本文提出了一种采用六项余弦偶次幂窗三峰插值的算法来对电网谐波进行检测与分析。该算法通过分析电网信号加窗后傅里叶变换的频域表达式,利用谐波频点附近的三根离散频谱的幅值确定谐波谱线的准确位置,进而得到电网谐波的相关参数频率、幅值及相位的计算公式,最后再对其进行加权修正,从而进一步的提高检测的准确度和有效性。( this paper proposes an approach for power network harmonic detection and analysis based on six even order cosine window and triple-spectrum-line interpolation. Through analyzing the adding window signal fourier transform in the frequency domain expression, using amplitude of three discrete spectrum near the harmonic frequency point to determine the accurate position of the harmonic spectrum and get the calculation formula of related parameters of the power network harmonic such as frequency, amplitude and phase, the algorithm further enhances the accuracy and effectiveness by using weighted correction.)
