Abstract

This paper investigates bipartite consensus of multi-agent systems under unknown false data injection attacks. Attacks are launched in the channels from the controller to the actuator. To compensate the impact of attacks, an extended observer including the absolute output information is firstly constructed, and then an observer-based event-triggered controller is designed to save resources. Moreover, an observer-based fully asynchronous event-triggered controller is proposed to further reduce the communication cost. Sufficient criteria are deduced to guarantee bipartite consensus and Zeno behavior is further ruled out. Finally, numerical examples are given to illustrate the effectiveness of the derived results.
