摘要：This paper discusses the design of event-triggered output-feedback controller for a class of nonlinear time-delay systems with multiple uncertainties.In sharp contrast to previous works,the considered systems possess two important characteristics:(ⅰ)The uncertain nonlinear terms meet the linearly unmeasurable-states dependent growth with the growth rate being an unknown function of the input and output.(ⅱ)There exist input matching uncertainty and unknown measurement sensitivity.By introducing a single dynamic gain and employing a cleverly devised event-triggering mechanism(ETM),we design a new gain-based event-triggered output-feedback controller,which globally regulates all states of the considered systems and maintains global boundedness of the closed-loop system.Furthermore,the estimation of input matching uncertainty achieves convergence towards its actual value,and Zeno behavior does not happen.Two simulation examples including a practical one show that the proposed approach is effective.
