Fault detection for Networked Control System with multiple Communication Delays and multiple missing measurements

This paper is concerned with fault detection problem for a class of Networked Control Systems (NCSs) with both multiple Communication Delays and multiple missing measurements. In this paper we build up a fault detection filter through a model of NCS, so that the overall fault detection dynamics is exponentially stable in the mean square, besides the error between the residual signal and the fault signal is made as small as possible. Sufficient conditions are first established for the existence of the desired fault detection filters, and then, the corresponding solvability conditions for the desired filter gains are established. At the end of this title, a simulation example was given to demonstrate the effectiveness of the proposed method.
