Monitoring independent components for fault detection
TL;DR: In this paper, a new statistical process control method based on Independent Component Analysis (ICA) is proposed, and its fault-detection performance is evaluated and compared with that of the conventional multivariate statistical process Control (cMSPC) method using principal component analysis by applying those methods to monitoring problems of a simple four-variable system and a continuous-stirred-tank-reactor process.
Journal ArticleDOI
Comparison of multivariate statistical process monitoring methods with applications to the Eastman challenge problem
Manabu Kano,Koji Nagao,Shinji Hasebe,Iori Hashimoto,Hiromu Ohno,Ramon Strauss,Bhavik R. Bakshi +6 more
TL;DR: In this paper, two advanced methods, moving principal component analysis (MPCA) and DISSIM, have been proposed to improve the performance of multivariate statistical process control (MSPC).
Journal ArticleDOI
A new multivariate statistical process monitoring method using principal component analysis
TL;DR: In this paper, the authors proposed a moving principal component analysis (MPCA) method to monitor the correlation structure of process variables, instead of changes in the scores of predefined principal components.
Journal ArticleDOI
Evolution of multivariate statistical process control: application of independent component analysis and external analysis
TL;DR: External analysis is proposed to distinguish faults from normal changes in operating conditions and to further improve the monitoring performance, a new MSPC method based on independent component analysis (ICA) is used.
Journal ArticleDOI
Statistical process monitoring based on dissimilarity of process data
TL;DR: The results clearly show that the monitoring performance of DISSIM, especially dynamic DIS SIM, is considerably better than that of the conventional MSPC method when a time-window size is appropriately selected.
