A Distributed Cooperative Guidance Law with Prescribed-Time Consensus Performance

This paper proposes a prescribed-time convergent distributed cooperative guidance law that enables aircraft to reach the same location in a cooperative manner in both undirected and directed communication topologies. First, the heading error angle is designed to derive the analytical expression of the flight time. Then, the guidance law is incorporated as a bias term into the heading error angle to ensure that the remaining flight time error converges to zero within the prescribed time so as to realize the cooperative arrival of the aircraft at the same location. Finally, numerical simulations were conducted to verify the effectiveness of the proposed algorithm under both communication topologies.
