This paper investigates the event-triggered output feedback adaptive fuzzy fault-tolerant con-trol problem for switched nonlinear systems with actuator faults.Firstly,A mode-dependent state ob-server 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 re-duce 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 phe-nomenon can be excluded.Finally,the effectiveness of the method is verified by simulation result.
