Summary:Dear Editor, This letter investigates global stabilization of uncertain nonlinear systems via adaptive event-triggered output feedback. Uncertainties lie in both system nonlinearities and measurement sensitivity. To this end, a dynamic high gain is introduced to cope with the influence of large uncertainties, the unknown measurement sensitivity and the execution error, while a time-varying threshold event-triggering mechanism is constructed to effectively exclude the Zeno phenomenon. As such, the adaptive event-triggered control ensures globally bounded and convergent of system states. The design method is demonstrated using a controlled pendulum example.
