Reliable H∞ output control of nonlinear systems with dynamic event-triggered scheme.

Highlights • A dynamic event-triggered mechanism is proposed to regulate the triggering threshold with respect to system output. • Considering actuator executing with failures, the fault parameters are estimated adaptively to offset the fault affects to systems. • New technique is developed to treat the controller synthesis. Abstract This paper is concerned with the reliable event-triggered H ∞ output control of nonlinear systems with actuator faults. A dynamic triggering scheme depending on system outputs is implemented to reduce the amount of communication transmissions, which is different from existing constant triggering thresholds. The parameters of actuator faults are estimated via observer state. To compensate for the fault effects on systems, the reliable controller parameters are adjusted along with the obtained estimations. By using some technical lemmas, new sufficient conditions for the closed-loop system to be asymptotically stable with prescribed H ∞ performance are formed in linear matrix inequalities. Lastly, simulations are implemented to demonstrate the validity of the proposed method. [ABSTRACT FROM AUTHOR]
