Abstract: This paper investigates the three-dimensional cooperative operation for multiple flight vehicles. Based on the leader-follower structure, two distributed cooperative guidance strategies are presented to achieve simultaneous arrival of the vehicles. The first strategy enables the states of followers to synchronize with that of the leader via consensus control of the selected cooperative variables. In the other strategy, a distributed observer is proposed to estimate the state of the leader accurately, and the followers track the estimated information to obtain simultaneous arrival with the leader. Theoretical analysis indicates that all the flight vehicles governed by the two strategies can strike the target simultaneously. The simulation results validate the correctness and effectiveness of the proposed strategies.

Key words: cooperative guidance, leader-follower flight vehicle, simultaneous arrival, distributed observer, consensus control
