摘要
阐述了航天器自主运行的概念、目标和任务。对自主运行和传统测控方式进行了比较。最后重点介绍了航天器自主运行技术的进展情况。文章分 4个部分介绍自主运行技术。首先介绍了 2种自主运行体系结构 ,它们是自主运行各种功能集成的基础。第 2部分介绍了 2种智能规划与调度技术。第 3部分介绍了基于模型的故障诊断与系统重构技术。第 4部分介绍了有效载荷数据自主处理的进展情况。
The concept and goals for autonomous spacecrafts are defined.The spacecraft autonomous control system is compared with the traditional spacecraft control system.The advantages of autonomous control are given.Then we describe the technical overview of autonomous control and on board data processing from 4 aspects.The autonomy architecture of spacecraft,which integrates all kinds of autonomy function,is particular important for autonomous spacecrafts to work efficiently.So two different structures developed by NASA are discussed firstly.Then,three important technologies of autonomy are introduced respectively.First,two kinds of intelligent planning and scheduling methods are discussed.Second,model based fault diagnosis and system reconstruction are discussed.Third,two examples of on board data processing are introduced.At last,we discuss the related technologies with autonomy.
