The invention relates to a multi-phase batch process phase dividing method based on a multiway principal component analysis method, which comprises the following steps: model data acquisition, three dimensional data expansion, two dimension matrix standardization, PCA decomposition, principal component ...
Classification of sags gathered in distribution substations based on multiway principal component analysis Voltage sags, whether they occur in transmission or distribution systems, may severely damage the loads connected to the power system. As these problems co... A Khosravi,J Meléndez,J Colomer -...
Process substage separation is realized because the loading matrices and the singular value matrices in the same operation substage are with great similarity. Based on the improved stages separation method, the multiway principle component analysis(MPCA) modeling is applied to online monitoring and ...
Batch processes lie at the heart of many industries; hence the effective monitoring and control of batch processes is crucial to the production of high-quality materials. Multiway principal component analysis (MPCA) has been widely used for batch monitoring and has proved to be an effective method...
Batch processes play an important role in the production of low-volume, high-value products such as polymers, pharmaceuticals, and biochemical products. Multiway principal component analysis (MPCA), a multivariate projection method, has been widely used to monitor batch processes. But in-control data...

Adaptive multiway PCA (MPCA) models are developed to update the covariance structure at each scale to deal with changing process conditions. Process monitoring by a unifying adaptive multiscale MPCA involves combining only those scales where significant disturbances are detected. This multiscale approach...
