摘要
首先提出了一种包括规划与调度、执行以及执行监控与故障诊断的航天器自主控制系统。在此基础上,重点针对航天器分系统众多、组成复杂、知识表示困难的特点,提出了基于分层结构的航天器自主规划与调度系统的设计方法。该方法能够有效地表示和管理航天器的相关知识,并能根据给定的高级任务目标,结合自身状态进行推理,搜索出合理的指令序列,当发生故障或其他紧急情况时,能够进行重规划。
An autonomous spacecraft control system including planning and scheduling, command execution, execution surveillance, and fault diagnosis was presented. On the basis of the system and consideration of many sub-systems, complicated configuration, and difficult knowledge expression in spacecraft, a design method of autonomous planning and scheduling system based on hierarchical structure was given. This method can effectively express and manage knowledge about the spacecraft propose high level goals, as well as search for reasonable command sequence according to the state of the spacecraft. When some fault or emergency occurs, this method can conduct re-planning and rescheduling.
