Abstract
This paper investigates the adaptive event-triggered tracking problem for high-order nonlinear systems with deferred asymmetric time-varying full-state constraints. Firstly, a shifting function is introduced to remove the constraint bounds of the system state’s initial value, and a novel time-varying nonlinear function is adopted to deal with the asymmetric full-state constraints. Secondly, a coordinate transformation combining dynamic surface technology is proposed to remove the feasibility condition on virtual controllers. Then, an adaptive state-feedback event-triggered controller is designed to guarantee that the closed-loop system is stable and the asymmetric full-state constraints are maintained. Finally, the simulation is provided to illustrate the effectiveness of the control scheme.
