| Abstract: | This paper investigates the event-triggered output feedback adaptive fuzzy fault-tolerant control problem for switched nonlinear systems with actuator faults. Firstly, A mode-dependent state observer is established to estimate unmeasured states. Fuzzy logic systems are employed to approximate the unknown uncertainties. The constructed adaptive fuzzy fault-tolerant event-triggered controller can reduce the usage of the communication resources. Then, by multi-Lyapunov functions and average dwell time method, it is proved that all states of the closed-loop systems are SGGUB. In addition, zeno phenomenon can be excluded. Finally, the effectiveness of the method is verified by simulation result. |
