Abstract
Wireless solar blind ultraviolet (UV) scattering communication is a new type of atmosphere optics communication technology with the important and potential advantages of all-weather, non-line-of-sight and secret communication, which is suitable for the needs of cluster security of Unmanned Aerial Vehicle (UAV) formation flight. UV communication technology can be applied to share UAVs status information, combined with efficient formation control method can achieve autonomous assembly, collision avoidance and formation keeping in UAV formation flight. In order to avoid the collision avoidance problem between the UAVs in the classic formation control algorithm. In this paper, the artificial potential function of the formation control algorithm is improved and the improved algorithm is applied to a single virtual leader UAV and multi-virtual leader UAVs. The simulation results show that the algorithm can ensure that the UAVs speed in the formation is consistent with the speed of the virtual leader UAV. In the course of the flight, the UAVs can avoid collision. Finally, the formation flight is completed with the desired formation.
