Abstract

Problems related to fault detection of networked control systems have been studied in this paper. The influence of unknown and random network-induced delay on conventional fault detection systems based on parity relation and H₂ optimization is first analyzed. Then a new procedure for designing fault detection systems for networked control systems with random network-induced delay and unknown inputs based on stationary wavelet transform and parity relation is proposed. The residual generator designed with the new approach is robust to both the random network-induced delay and the unknown input
