![عکس صفحه اول مقاله: Modeling and monitoring of multimode process based on subspace separation Modeling and monitoring of multimode process based on subspace separation](/preview/png/621527.png)
In the paper, a new process monitoring approach is proposed for handling the multimode monitoring problem in the industrial batch processes. Compared to conventional method, the contributions are as follows: a new method of extracting the common subspace of different modes is proposed based on the subspace separation; after that the two different subspaces are separated, the kernel principal component models is built for the common and specific subspace respectively and the monitoring is carried out in subspace. The monitoring is carried out in the subspaces. The corresponding confidence regions are constructed according to their models respectively.
► Subspace separation method of the multimode process is proposed.
► Confidence regions are constructed according to the process models.
► Fault detection method in the multimode process is proposed.
