聚类分析里的k均值（kmeans）算法的matlab实现，是老师即将出的书里，我给写的例子，大家看看吧。 (Where k-means cluster analysis (kmeans) algorithm matlab implementation, a teacher is leaving the book, I give examples of writing, we take a look at bar.)

对电网不平衡情况下的三相PWM整流器进行了详细的建模分析，并在此基础上研究了两种不平衡控制策略。其一是抑制网侧负序电流的控制策略，主要控制三相PWM整流器交流电流对称正弦化控制。其二是抑制直流电压谐波分量的控制策略，主要控制三相PWM整流器从电网吸收平衡的瞬时功率，消除直流电压中的各次谐波分量。(Research on the Control strategy of Three-Phase PWM Rectifiers under Unbalaneed Grid Voltage)
