代码说明:

PCA故障诊断方法是典型的数据驱动建模的一种故障诊断方法。利用PCA进行故障诊断分为四步:数据采集,数据归一化,计算SPE和T^2统计量以确定是否发生故障,计算故障点贡献率以确定发生故障的变量。

    KPCA 的基本思想是将数据从输入空间映射到高维特征空间,然后在特征空间利用线性主成分分析方法计算主成分。本程序是KPCA的源程序,可实现调用。对于初学者或许有帮助。(The basic idea of KPCA is to map the data from the input space to high dimensional feature space, then in the feature space using principal component analysis method to calculate the linear principal components. This program is the source KPCA can achieve call. May be helpful for beginners.)
