Under the assumptions of network-induced time delay being unknown but bounded, packet dropouts and packets out of sequence being unavoidable, a system model for networked control system is firstly introduced in the continuous-time domain. Then an observer-based H∞ fault detection is formulated and, by applying the Lyapunov-Krasovskii functional approach, a delay-dependent sufficient condition on the existence of the H∞ fault detection filter (FDF) is derived in terms of matrix inequality. Furthermore, an algorithm is proposed to get a feasible solution to the H∞ fault detection filter gain matrices in terms of linear matrix inequalities (LMIs) using a cone complementary technology. A simulation example is given to demonstrate the effectiveness of the proposed method.en-USAutomatic controlComputer networksTime delay systemsFault location (Engineering)Article
