Abstract

A new approach for Fault Detection (FD) of Networked Control Systems (NCSs) based on Parity Relation (PR) and Principal Component Analysis (PCA) is proposed in this paper. The method can realize a good decoupling from unknown and random network-induced delay, and further ensure the robustness to traditional unknown inputs under an optimization sense. The approach is compared with the traditional PR based FD method for systems without network-induced delay and the existing PR based method for FD of NCSs.
