Abstract

This paper deals with the fault detection problem for a class of discrete-time networked systems with random delays and disturbance. With the maximum allowable delay, a binary stochastic switching sequence is used to simplify the FDI for NCS. Attention is focused on the design of a fault detection filter, which can be robust for the unknown disturbance. A sufficient condition for the existence of the desired fault detection filter is established in terms of a linear matrix inequality (LMI). A numerical example is provided to illustrate the feasibility and applicability of the proposed techniques.
