摘要:

设计新的粒子群(PSO)算法的粒子结构,以解决智能弹群任务分配问题。首先,引入战场态势信息以确定智能弹群任务时间窗口,并将其融入任务分配数学模型。其次,基于快速搜索随机树(RRT)算法,在任务分配阶段完成躲避禁飞区的航迹规划,以减小实际航程与预估航程之间的差异,确保分配结果的合理性,使优化结果更具实际意义。最后,在不同任务规模下将所提出的算法与遗传算法和禁忌搜索算法结果进行仿真对比分析,所得结果验证了本文方法的原理简单、参数较少、计算代价小、更易于智能弹群任务分配问题的实际工程应用。

Abstract:

A new particle structure of Particle Swarm Optimization (PSO) is proposed to solve the task assignment problem of the intelligent missile swarm. Firstly, the battlefield situation information is introduced to determine the task time window of the intelligent missile swarm, and further integrated into the task allocation mathematical model. Secondly, based on the Rapidly-exploring Random Trees (RRT) algorithm, the flight path planning of avoiding no-fly zones is completed in the task assignment stage to reduce the difference between the actual distance and the estimated distance, and to ensure the rationality of the assignment result, so that the optimized results are more practical. Finally, the proposed algorithm is compared with the results of the genetic algorithm and tabu search algorithm under different task scales, and the simulation results verify that the proposed method has simple principles, fewer parameters, lower calculation costs, and is easier to apply in practical engineering of intelligent loitering munition swarm task assignment problems.

Key words: intelligent missile swarm, task assignment, particle swarm optimization, particle structure, Rapidly-exploring Random Trees (RRT)
