一种基于M-ary支持向量机的功率变换器故障分类方法
Fault Classification of Power Converters Based on M-ary Support Vector Machine Method
摘要
Abstract
Focusing on the issue of power converter fault diagnosis and location, a genetic algorithm based M-ary support vector machine (SVM) was proposed to enhance the accuracy of fault classification. The proposed method used the genetic algorithm and the within-class and between-class distance criterion to find the suboptimum fault coding which is related to the fault classes of power converters, and the optimized classifier model of M-ary SVM was established for the fault classification of power converters. The experiment results show that this optimized method has better fault classification accuracy than the standard M-ary SVM. Compared with the commonly used one-against-one SVM and one-against-all SVM, the proposed method needs far less number of classifiers and hence, the classification time can be reduced.关键词
