Event-Triggered Output-Feedback Control for High-Order Uncertain Nonlinear Multiagent Systems Subject to Denial-of-Service Attacks

This paper focuses on the cooperative control problem of multi-agent systems subject to limited energy supply, unreliable communication and malicious attacks on devices. As the advancement of network technology, Denial-of-Services attacks targeting multi-agent systems are prevalent. To detect the valid Denial-of-Services attacks, this paper designs a novel detection mechanism, which based on the voltage levels of the transceiver and receiver. Due to the state information may be more difficult to measure, the reduced order dynamic gain k-filters are designed to reconstruct the states based on only the system outputs. Then, based on the detection mechanism and estimated states, event-triggered resilient consensus controller and switched control strategy are designed, such that the multi-agent systems achieve leader-following consensus with less consumption of energy and nice resilience to Denial-of-Services attacks. Finally, a simulation example is presented to demonstrate the effectiveness of the obtained theoretical results.
