斜交主元分析方法及其在故障诊断的应用

Oblique Principal Component Analysis

针对主元分析(PCA)方法的特点,对其进行了拓展性研究。该方法针对主元分析的主元是正交的,而主元代表的现实事物的基本特征间往往存在一定的相关性。因此提出了斜交主元分析方法,并对斜交主元分析方法的理论体系及其应用进行了初步的探讨。

With reference to the characteristics of the oblique principle component analysis, the article conducts an exploring research with purpose of improving its monitoring sensitivity and diagnosing accuracy. The principle component used for principle component analysis is orthogonal,while the reality represented by the principle component possesses a definite relationship in regard to its basic specialty. The article proposes the method for oblique principle component analysis（OPCA）,and conducts a preliminary study on the theoretical system of the method of OPCA,and on its application.
