When multi-dynamic target UAVs escape, the uncertainty of the formation method and the external environment causes difficulties in rounding them up, so suitable solutions are needed to improve the roundup success rate. However, traditional methods can generally only enable the encirclement of a single target, and when the target is scattered and escaping, this will lead to encirclement failure due to the inability to sufficiently allocate UAVs for encirclement. Therefore, in this paper, a real-time roundup and dynamic allocation algorithm for multiple dynamic targets is proposed. A real-time dynamic obstacle avoidance model is established for the roundup problem, drawing on the artificial potential field function. For the escape problem of the rounding process, an optimal rounding allocation strategy is established by drawing on the linear matching method. The algorithm in this paper simulates the UAV in different obstacle environments to round up dynamic targets with different escape methods. The results show that the algorithm is able to achieve the rounding up of multiple dynamic targets in a UAV and obstacle scenario with random initial positions, and the task UAV, which is able to avoid obstacles, can be used in other algorithms for real-time rounding up and dynamic allocation. The results show that the algorithm is able to achieve the rounding up of multi-dynamic targets in scenarios with a random number of UAVs and obstacles with random locations. It results in a 50% increase in the rounding efficiency and a 10-fold improvement in the formation success rate. And the mission UAV is able to avoid obstacles, which can be used in other algorithms for real-time roundup and dynamic allocation.
多动态目标无人机逃逸时,编队方式和外部环境的不确定性给围捕带来困难,因此需要合适的解决方案来提高围捕成功率。然而,传统方法通常只能实现对单个目标的包围,当目标分散逃逸时,由于无法充分分配无人机进行包围,会导致包围失败。因此,本文提出了一种针对多个动态目标的实时围捕与动态分配算法。针对围捕问题,借鉴人工势场函数建立了实时动态避障模型。针对围捕过程中的逃逸问题,借鉴线性匹配方法建立了最优围捕分配策略。本文算法在不同障碍环境下对无人机进行仿真,以围捕具有不同逃逸方式的动态目标。结果表明,该算法能够在无人机和障碍物初始位置随机的场景中实现对多个动态目标的围捕,且能够避障的任务无人机可用于其他实时围捕和动态分配算法。结果表明,该算法能够在无人机数量随机、障碍物位置随机的场景中实现对多动态目标的围捕。围捕效率提高了50%,编队成功率提高了10倍。且任务无人机能够避障,可用于其他实时围捕和动态分配算法。
