Observer-based resilient control of multi-agent system under false data injection attacks

摘要

This paper studies event-triggered observer-based resilient control of linear multi-agent systems under false data injection attacks. It is assumed that false data is injected into the channel from the controller to the actuator. By considering the attack signal as the augmented state, event-triggered observers are designed to estimate system states and attack signals. Then observer-based resilient controller is proposed to counteract the impact of attacks. An sufficient condition is derived and the exclusion of Zeno behavior is discussed. One example is given to verify the feasibility of the proposed scheme.
