Observer-based Event-triggered Output Feedback Control for a Class of Uncertain Nonlinear Systems

This paper focuses on the observer-based event-triggered output feedback stabilization problems for a class of uncertain nonlinear systems. Under the assumption of the existence of a smooth Lyapunov function, the output feedback control strategy is designed and the considered system is asymptotically stable with the Zeno phenomenon being excluded. The strategy involves using the estimation output to generate the event-triggered control action. It is shown that the proposed event-triggered strategy could significantly save the resource. Finally, the effectiveness of the approach is evaluated through a simulation example.
