State-Based Dynamic Event-Triggered Observer for One-Sided Lipschitz Nonlinear Systems With Disturbances

Considering that the communication networks usually suffer from limited communication resources with detrimental consequences, this brief considers the state-based dynamic event-triggered observer issue for one-sided Lipschitz nonlinear systems (OLNSs) with disturbances. To reduce the supervision time, a discrete-time event-triggering mechanism (DETM) is proposed in accordance with sampled signals (SSs) and a dynamic function, which not only significantly reduces the utilization of communication resources but also maintains the desired system performance. Then, by resorting to an input-delay protocol, sufficient conditions are derived to guarantee that the state observer can availably estimate the state of the system. An illustrative example is provided to verify the merit of the achieved strategy.
