摘要:
面对深空探测过程中环境的不确定性和扰动,航天器需要利用任务规划技术实现自主控制。航天器应用规划算法时,需要考虑到执行活动时满足的时间约束和资源约束。通过分析资源约束之间的关系,提出了可重复资源在规划执行时的可分配处理方法,和判断资源变量是否满足的可分配性条件。通过航天器仿真算例,验证了可重复资源的可分配处理方法在规划执行时的有效性。

Abstract:
Considering the uncertainty and disturbance of environment in deep space exploration, spacecraft need to use mission planning technology to realize autonomous control. When a spacecraft applies the planning algorithm in aerospace engineering actirities, the time constraints and resource constraints should be considered. By analyzing the relationship between resource constraints, the dispatchable processing method of reusable resources in the execution of planning and the standard to determine whether resource value is dispatchable are proposed. Through the spacecraft simulation example, the dispatchable processing method of reusable resource in planning implementation is demonstrated to be valid.
