Monitoring of Multimode Processes Based on Quality-Related Common Subspace Separation

الملخص EN

A new monitoring approach for multimode processes based on quality-related common subspace separation is proposed.

In the model, the data set forms a larger space when the correlation between process variables and quality variables is considered.

And then the whole space is decomposed: quality-related common subspace, quality-related specific subspace, and the residual subspace.

Monitoring method is performed in every subspace, respectively.

The simulation results show the proposed method is effective.
