Fault detection of networked control systems (NCS) with communication constraints is discussed in this paper. A so-called packet-based periodic communication strategy is proposed and two kinds of optimal observer-based residual generators are designed. One residual generator is designed based on the lifted model of NCS, which generates residual signals every communication period. The other works at a faster rate, i.e. it generates residual signals every sampling period and is more suitable for prompt fault detection. Comparison with traditional periodic-communication-sequence-based scheduling strategy reveals superiority of this new communication strategy. Simulation results are also provided to illustrate effectiveness of the proposed method. Copyright © 2008 John Wiley & Sons, Ltd.
