摘要
匹配算法。根据小波分析和人工免疫系统的原理 ,提出了一种基于小波变换和免疫系统的故障诊断系统。针对小波分析的特点 ,将其用来对非稳定信号进行分析 ,获取信号特征向量作为原始数据 ,利用匹配算法对原始数据进行己 -非己分析。将此系统应用到车辆总成故障诊断中 。
A fault diagnosis system based on the wavelet transform and artificial immune system is presented,in which the wavelet transform is used to analyze non-stable signals and obtain their eigenvectors.A matching algorithm is also proposed to conduct self-nonself analysis based on these eigenvectors.The system is successfully applied to vehicle fault diagnosis with good results.
