Dynamic Event‐Triggered Output Feedback Control for a Class of Uncertain Nonlinear Systems

Abstract

In this article, the dynamic event‐triggered output feedback control problem for a class of uncertain nonlinear systems is studied. Since system states are not available for controller design, a state observer is designed to estimate them. On the basis of the estimated states, a dynamic event‐triggered control scheme is proposed. Compared with existing event‐triggered schemes, a dynamic auxiliary variable is added in the event conditions. By properly designing the dynamics of the auxiliary variable, it is proved that the tracking/stabilization error is able to converge to zero without the presence of Zeno behavior. The effectiveness of the control scheme is verified by simulation results.
