The problem of event-triggered networked fault detection for positive systems with Markovian parameters is investigated in this paper. A dynamic linear event-triggered scheme is proposed to limit the quantity of the transmitted data in the communication channel. With the consideration of network-induced delays, a networked fault detection filter is designed as a positive Markov jump system to detect the fault signal. ℓ1-gain performance is taken into account to study the disturbance attenuation. Through linear Lyapunov function method, the criteria for the solvability of the concerned problem are presented. The parameters of proposed event-triggered condition and desired fault detection filter can be further determined through solving obtained linear programming (LP) problems. Two illustrative examples are given to demonstrate the effectiveness of the theoretical results.
