摘要
主元分析(PCA)已广泛应用于监视多变量过程,但PCA不能有效地监视动态多变量过程.动态主元分析(DPCA)是一种将静态PCA推广应用到监视动态多变量过程的方法.本文通过实例验证了DPCA监视动态多变量过程的有效性.
Principal component analysis(PCA) has been widely used for monitoring multivariate process, but PCA can not monitor dynamic multivariate process .Dynamic principal component analysis(DPCA) is a method by extending static PCA to monitor dynamic multivariate process. The paper verifies the effectiveness of DPCA for monitoring dynamic multivariate process.
