Abstract: This article focuses on the event-triggered fault-tolerant control (ETFTC) for a family of nonlinear pure-feedback systems (PFSs) is investigated. Firstly, the differential mean-value theorem (MVT) is applicable to deal with the nonaffine function in systems and the control input signals were successfully decoupled. Then, by using backstepping technique and the fuzzy logic systems (FLSs), a novel finite-time ETFTC scheme is effectively rendered. Furthermore, the newly designed fault-tolerant controller compensates for actuator faults, the trigger mechanism improves the transmission efficiency of the input signals, and the ETFTC scheme guarantees that all closed-loop signals are bounded. Comparative simulation results further validate the effectiveness of the given control method.
