摘要
针对多星组网对地观测中的任务协同分配问题,本文提出了一种基于合同网络算法的星间任务分配方法。建立了面向分布式敏捷卫星多种协同工作模式的任务分配模型,设计了分配结果收益计算模型;采用合同算法中的买卖、交换及置换等策略,进行观测任务的拍卖与分配。分别以4颗星和7颗星组网方式进行任务分配算法的仿真验证,结果表明:得到的分配结果有效可行,且分配时间短效率高。本文提出的算法能够有效解决任务分配问题。
To solve the problem of cooperative task allocation in multi-satellite network observation,we propose an inter-satellite task-allocation method based on a contract network algorithm,establish the task assignment mathematical model for distributed agile satellite′s multi-collaboration working mode,and design the task revenue calculation model.Then,the auction,exchange,and replacement strategies in the contract algorithm are used to auction and distribute the observation task.Finally,a simulation using the task assignment algorithm was carried out in the four-star and seven-star networking modes.The results show that the proposed algorithm is feasible,effective,and highly time-efficient,demonstrated by the short assignment-completion time;therefore,it is effective for solving task assignment problems.
