Decentralized Event-Triggered Output Feedback Control for Nonlinear Networked Interconnected Systems under Multiple Cyber Attacks

This paper investigates the decentralized event-triggered output feedback control for nonlinear networked interconnected systems under multiple cyber attacks, where denial of service and deception attacks are considered. A resilient period event-triggered strategy is adopted to reduce the occupation of network resources. Considering the impact of cyber attacks, the output-based decentralized security controller is constructed within a unified framework. Sufficient conditions of stochastically finite-time stable of the switched system are given by employing the Lyapunov-Krasovskii functional. Then, the controller gains and event-triggered weight matrix are designed simultaneously. Finally, a chemical reactor system is used to substantiate the effectiveness of the proposed method.
