摘要

摘要: 针对无人机集群在特定场景下需要在指定区域安全、快速集结成指定队形的需求，该文提出了一种分区集结的控制策略。考虑无人机(UAV)的初始分布位置、集结区域以及编队图案等约束，为每架UAV分配目标集结点并使总航程尽量小。将近集结点区域等分为多个分区，不同分区内的UAV均按一定规则依次沿直线向所分配目标集结点航行，无多余航路能耗且互不影响。UAV间通过紫外光进行稳定的机间通信并共享已知信息实现集群内部信息共享。实验结果表明：随着分区数的增多，集群的集结时间呈阶梯型下降，阶梯高度与各分区所含UAV数目的最大值呈近似线性关系，预测碰撞概率逐渐降低接近于0，验证了所提方法的可行性和有效性。另外，根据实验结果得出的规律提出了一种依据不同需求选择最佳分区数的方法。

Abstract: In order to make the Unmanned Aerial Vehicle (UAV) swarm arrival into the specified place quickly and safely, a control strategy of partition rendezvous is proposed. Considering the start distribution position of each UAV, rendezvous area and formation pattern, target rendezvous point are assigned for each UAV and the total range is minimized. The area near the rendezvous point is divided into several zones. UAVs in different zones travel in a straight line to the target rendezvous points in turn according to certain rules, without excess air route energy consumption and without mutual influence. UAVs communicate with each other stably through ultraviolet light, and share known information to realize information sharing within the swarm. The experimental results show that with the increase of the number of zones, the time taken to rendezvous decreases in a stepped manner. There is an approximate linear relationship between the height of the steps and the maximum number of UAVs in each zone, and the prediction of collision probability gradually decreases and finally approaches 0. In addition, a method to select optimal number of zones according to different needs is proposed.
