Abstract: The paper investigates the event-triggered control problem for fault tolerant control system with actuator failure and randomly occurring parameter uncertainty. Firstly, the hybrid event-triggered control scheme is adopted for the fault tolerant control system subjected to actuator failure and randomly occurring parameter uncertainty in this paper, which could greatly decrease the amount of network data transmission and save communication resources. By utilizing the delay system method, the event-triggered fault tolerant control system is modeled as a delay system. Then, by constructing appropriate Lyapunov–Krasovskii functional, sufficient conditions are derived in form of linear matrix inequalities (LMIs) to guarantee the system is stochastically passive with prescribed passive performance γ. The impact of the actuator fault and the random occurring parameter uncertainty are studied under the unified framework. Eventually, two simulation examples including F-404 aircraft engine system are presented to illustrate the effectiveness of the proposed theoretical findings.
