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.
