Resilient Event-Triggered H∞ Control Under DoS Attacks With an Application to Offshore Structures

This article focuses on the resilient event-triggered
$H_{\infty }$
control for networked control systems (NCSs) against external disturbances and network constraints on communication delays, efficiency, and attacks. First, a resilient event-based mechanism is presented considering the consequences of the DoS attacks disruption, where resilience refers to the tolerance of the attack behavior during data triggering. Then, the studied system is integrated into a class of switching time-delay systems, and a series of sufficient conditions are derived to ensure the internally exponential stability of the system and to design the resilient event-triggered
$H_{\infty }$
controllers. Particularly, the relationship between attack periods, network-induced delays, and decay coefficients is identified, which potentially forms an early warning of attacks. Finally, the effectiveness of the proposed methods is examined through application to a networked offshore structure system.
