结合PCA的尺度不变特征变换(SIFT)算法，DC-DC部分采用定功率单环控制，Relief计算分类权重，最终的权值矩阵就是滤波器的系数，使用混沌与分形分析的例程，信号处理中的旋转不变子空间法。- Combined with PCA scale invariant feature transform (SIFT) algorithm, DC-DC power single-part set-loop control, Relief computing classification weight, The final weight matrix is ??the filter coefficient, Use Chaos and fractal analysis routines, Signal Processing ESPRIT method.
