Event-Triggered Control for Nonlinear Systems: A High-Order Full-Actuation Approach

In this paper, a novel event-triggered stabilization control scheme is developed for a class of nonlinear systems in strict-feedback form. By utilizing the high-order full-actuation (HOFA) theory, an explicit design process of ideal controller is proposed for the system. Then, an actual control input based on event-sampled variables is designed to improve communication efficiency. Compared with the existing event-triggered control algorithm via the HOFA theory, the proposed control strategy can reduce the transmission frequencies of the dual channels. Meanwhile, the current state information is considered in the designed adaptive threshold which can obtain suitable triggering step sizes. Finally, by combining the impulsive dynamic analysis method and Lyapunov stability theorem, it is proved that all states of the closed-loop system are kept uniformly ultimately bounded. The effectiveness of the proposed scheme is demonstrated by a simulation example.
