摘要

In this paper, a new online monitoring approach is proposed for handling the dynamic problem in industrial batch processes. Compared to conventional methods, its contributions are as follows: 1) multimodes are separated correctly since the cross-mode correlations are considered and the common information is extracted; 2) the expensive computing load is avoided since only the specific information is calculated when a mode is monitored online; and 3) after that, two different subspaces are separated, and the common and specific subspace models are built and analyzed, respectively. The monitoring is carried out in the subspace. The corresponding confidence regions are constructed according to their respective models.
