Abstract

Abstract: Multi-way principal component analysis (MPCA) is the most widely utilized multivariate statistical process control method for batch processes.Previous research on MPCA has commonly agreed that it is not a suitable method for multiphase batch process analysis.In this paper,abundant phase information is revealed by way of partitioning MPCA model,and a new phase identification method based on global dynamic information is proposed.The application to injection molding shows that it is a feasible and effective method for multiphase batch process knowledge understanding,phase division and process monitoring.

Key words: batch process, multi-way principal component analysis, multiphase, process monitoring
