摘　　要：针对卫星机动能力提升和场景需求更加复杂的实际,设计了一种面向智能敏捷卫星的启发式调度方法。基于智能敏捷卫星系统,给出了调度问题的模型化描述;在此基础上,给出了滚动调度的自主任务规划调度框架,并基于系统延时指令和实时指令两个工作模式,在调度时机决策上分别采用混合触发机制和动态触发机制,并在调度算法上分别采用基于规则和优先级的启发式算法。另外,为了验证模型与算法在实际星上环境的表现,在板卡硬件上完成调度系统的设计与实现,并进行仿真实验,用以测试硬件系统的调度效果和延迟时间。To cope with the actual situation of increasing task planning maneuverability and more complex scene requirements,a scheduling method for intelligent agile satellite was designed.Based on intelligent agile satellite system,the model description of scheduling problem was given.On this basis,the autonomous task planning and scheduling framework of rolling scheduling was presented.Based on the two working modes of system delay instruction and real-time instruction,the hybrid trigger mechanism and dynamic trigger mechanism were adopted respectively in scheduling timing decision,and the heuristic algorithm based on rules and priority was adopted respectively in scheduling algorithm.In addition,to verify the performance of the model and algorithm in the actual onboard environment,the scheduling system was designed and implemented on the board hardware,and simulation experiments were carried out to test the scheduling effect and delay time of the hardware system.
