摘　　要：以中继卫星(Racking and Data Relay Satellite,TDRS)为研究对象,以有色Petri网(Colored Petri Net,CPN)为数学工具,根据自顶向下的原则和层次化建模思想,提出一种基于CPN的TDRS操作规划模型,该模型分为顶层模型、控制模型、前向链路数据接收任务与发送任务的操作规划模型和返向链路数据接收任务与发送任务的操作规划模型,有效地描述了TDRS的动态行为特性。最后,通过仿真实验得到了TDRS操作规划方案,验证了所建模型的有效性。与PDDL模型比较分析表明:所建模型可以有效引入TDRS的领域知识,能够有效提高求解效率。所建模型可以为TDRS操作规划方案的制定提供理论参考。According to the top-to-bottom concept and level modeling idea,and a new model of operation planning for Tracking and Data Relay Satellite(TDRS)is proposed by using Colored Petri Net(CPN).The model were divided into six modules as follows: top model,control model,operation planning model of forward and backward link data reception and transmission task,and it can describe dynamic behavior of TDRS. The scheme is obtained by designing typical example,and the proposed model is validated. Compared with Planning Domain Definition Language(PDDL)model,the proposed model can describe the domain knowledge of TDRS and has good solution efficiency. This work can provide theoretical basis for the scheme establishment of operation planning for TDRS.
