Event-triggered Distributed Cooperative Guidance for Multiple Aircraft

This paper investigates cooperative guidance problems under event-triggered scheme for multiple aircraft with fixed communication topology. The event-triggered distributed cooperative guidance method is divided into two steps. In the first step, an event-triggered scheme is proposed in the cooperative guidance method to reach consensus asymptotically. Each aircraft exchanges the state information with its neighbors at the certain instants when the states satisfy the triggering conditions. The frequency of the communication between the aircraft goes down compared with the periodic communication in the cooperative guidance method. In the second step, each aircraft adopt the widely-used proportional navigation guidance law (PNG) independently to conduct the cooperative mission without communication. Moreover, it is proven that the aircraft can fulfill the cooperative mission asymptotically under the designed triggering condition in the first step. Finally, simulation results are illustrated to verify the validity of the proposed cooperative guidance method under event-triggered scheme.
