面向多无人机协同对地攻击的双层任务规划方法

无人机(unmanned aerial vehicles, UAVs)的任务规划包含任务分配、执行顺序确定以及航迹优化等。为了达到任务规划的全局最优，需要全盘梳理任务的各个方面，提出高效的优化策略。综合考虑任务规划过程中任务分配、执行顺序确定以及航迹优化等方面的需求和相互间影响，首先从优化框架出发, 设计了双层互耦的任务规划求解策略, 而后将任务规划模型分为上层任务分配和下层任务序列优化, 并对每一层的优化方法和优化步骤进行了详细设计。在任务分配问题中, 基于模拟退火算法, 提出了可跳出局部最优的模拟退火-撒点(simulated-annealing-shooting, SAS)算法, 并详细探讨了算法参数的设计原则。最后通过仿真分析, 验证了所提出的规划框架和SAS优化算法的有效性。

Bi-level mission planning method for multi-cooperative UAV air-to-ground attack

The unmanned aerial vehicles (UAVs) mission planning consists of task allocation, mission sequence assignment and trajectory planning. These optimization problems are interacted. To achieve the global optimal solution of the UAVs mission planning, these three optimization problems should be fully considered and organized. In this paper, considering the requirements and interactions among the three optimization problems, a double-level planning framework is firstly introduced, and then the whole mission planning problem is decomposed into two parts: the high level task allocation and the low level sequence optimization. The optimization models and methods for each level are subsequently developed and detailed. In the process of task allocation, a simulated-annealing-shooting (SAS) is proposed for overcoming the local-optimal-trap, and the configuration principle of the algorithm parameters are discussed. Finally, the simulation results demonstrate the effectiveness of the proposed planning framework and the SAS algorithm.
