Dynamic Process Fault Isolation by Partial DPCA

摘要

Principal component analysis (PCA) is a popular tool in fault detecting of the complex plant,but offers little support on fault isolation.Partial PCA (PPCA) is well developed for its capability of fault isolation utilizing a structured residual.In this paper,partial dynamic PCA(PDPCA) is proposed to enhance the isolation ability of dynamic process,which is a method combining PPCA and dynamic PCA.Simulation of PDPCA on a CSTR shows the effectiveness of the proposed method.
