Aimed at any actuator fault with failure, the design of a hybrid active-passive robust $H_\infty$ fault-tolerant controller of uncertain nonlinear networked control system(NNCS) based on discrete event-triggered communication scheme(DETCS) is investigated, which has well rejection capability against external finite-energy disturbances. Firstly, a closed-loop fault model based on T-S fuzzy model is subsequently established for the uncertain NNCS under the DETCS. Then based on $H_\infty$ control theory, a fault detection observer is designed and the design criteria of robust $H_\infty$ fault-tolerant control for the uncertain NNCS is derived as well. Finally, Matlab numerical simulation results are presented to demonstrate the improvement of system performance benefits of the proposed control law and illustrate the saving of network resources derived from the introduction of event-triggered condition.
