Abstract

Purpose This work proposes a unified adaptive event-triggered tracking control scheme for high-order switched uncertain nonlinear systems, subject to asymmetric time-varying state constraints. The purpose of this paper is to guarantee closed-loop stability and boundedness under average dwell time switching while reducing communication load. Design/methodology/approach System uncertainties are approximated via neural networks, and finite-time differentiators are used to prevent the “explosion of complexity” in backstepping. High-order terms are handled with separable functions and auxiliary lemmas instead of power integrators. Furthermore, a universal-constrained nonlinear function and coordinate…
