摘要: The decentralized weighted ReliefF-PCA (DWRPCA) method is proposed to improve the performance of principal component analysis (PCA) for fault detection. improved algorithm used select components instead traditional cumulative percent variance (CPV) criterion, so that important information contained in small considered. sub-models different types faults which are being considered influence weights process variables and established respectively obtain model. Bayesian Information Criterion adopted integrate a unified monitoring index. case study numerical example Tennessee Eastman illustrate effectiveness method.
