Abstract

Principal component analysis (PCA) is a commonly used approach to process monitoring. However, it has been developed for singleton variables. Whereas, in many real life cases, this leads to a severe loss of information, this can be overcome by introducing the interval notion. The present paper deals with the study of fault detection and isolations (FDI) of uncertain process using interval PCA. Interval data are generated according to various models, and the FDI procedure is lead using the reconstruction principle technique, in its new interval form, for three interval PCA methods: Vertices PCA, Centers PCA, and Midpoints/Radius PCA. A comparison is presented where it is reported in which conditions each method performs best for FDI purpose.
