Asynchronous Periodic Event Triggered Output Feedback Control for Uncertain Feedforward Nonlinear Systems

ABSTRACT This article investigates the global output‐feedback stabilization for uncertain feedforward nonlinear systems via dual‐channel asynchronous periodic event‐triggered control. Based on the sampled states, periodic event‐triggered mechanisms that eliminate the need for continuous monitoring of system behavior are established to reduce the communication load on both sensor‐to‐controller and controller‐to‐actuator channels. Subsequently, an output feedback control scheme is proposed, wherein the time‐varying gain is crucial in effectively compensating for system uncertainties and sampling/actuator errors. In particular, the proposed control scheme exhibits greater flexibility, as the sampling periods of different triggering mechanisms can be set to different values without imposing strict constraints on their upper bounds. Based on the established control framework, further investigation is conducted on uncertain feedforward nonlinear systems with inherent time variations and low‐order powers.
