基于分布式ICA-PCA模型的工业过程故障监测
Fault monitoring of industrial process based on distributed ICA-PCA model
摘要
Abstract
A fault monitoring method based on distributed independent component analysis-principal component analysis (ICA-PCA) model is proposed, which is suitable for complex industrial process that cannot be divided into several sub-blocks through an automatic way and has non-Gaussian information. Firstly, an initial PCA decomposition is carried out upon the variables of the whole process. By constructing sub-blocks through different directions of PCA principal components, the original feature space can be automatically divided into several sub-feature spaces. In addition, a two step extractions of the ICA-PCA information are carried on upon all sub-blocks in order to extract both Gaussian and non-Gaussian information, establishing the new statistics and their statistic limits. Finally, the simulation of TE process shows that the proposed fault detection model is efficient and feasible.关键词
