To solve the problem of UAV rendezvous formation control for the formation consisting of a tanker and multiple receivers in the process of autonomous aerial refueling, a formation control approach is designed based on Lyapunov Guidance Vector Field (LGVF) and the information consensus theory.Firstly, the UAV formation models are established, including the communication topology model and the formation geometry model.Based on this, the cooperative variables of the multi-UAV system are defined.Then, the expected refueling trajectory is designed, and the flight control law of the tanker (the formations reference point) is designed based on the LGVF method.Then, according to the position and velocity information of the tanker, the UAV rendezvous formation control method is designed based on the consensus theory, and the stability of this method is analyzed.Finally, a numerical simulation is carried out to illustrate the effectiveness of the proposed method.
