Abstract
AbstractThis article proposes an adaptive event‐triggered output feedback tracking scheme for a class of nonlinear systems for which the system nonlinearities coupling with unmeasurable states satisfy a more general growth condition than those in the existing literature. To estimate the transformed state variables, a reduced‐order observer is first designed by using the gain scaling and estimation‐based techniques. Then, triggering conditions and event‐triggered control law are designed based on the dynamic gain, the observer states and the tracking error. It is shown that with the proposed scheme, the system communication and computation resources can be saved, the nonlinearities and the execution error can be compensated, and the tracking error can converge to an arbitrarily small residual set.
