Event-triggered interval estimation method for nonlinear system *

This paper presents a novel structure for the design of interval observers for continuous systems and introduces greater flexibility in parameter design compared to conventional interval observers. Additionally, an event-triggered mechanism(ETM) is employed to enhance the utilization of network resources and reduce computational overhead. Then the gain of the observer is solved by using a set of inequalities under sufficient conditions. Finally, the effectiveness of the designed interval observer is validated through numerical simulations.
