摘    要:本文介绍了一种关于时间逻辑的知识表示方法,引入了特征量属性及动态框架、事件、衍生事件的概念,给出了与时间有关的事件及包含事件间时间逻辑关系的衍生事件的表示方法,并将它们应用于航天器控制系统实时故障诊断专家系统中。这一研究是对时变系统深层知识表示方法的新探索。

关 键 词:专家系统,故障诊断,航天器控制系统

Abstract:This paper proposes a method of deep knowledge representation about time logic,introduces the concepts of characteristic attribute,dynamic framework,events and derivale events,offers a method of knowledge reprsentation about events involving time and derivative events which contains the logical time relations between events. The proposed method can be used to establish a real-time fault diagnosis expert system for spacecraft control system.This study is a new research about deep knowledge representation of time-varied systems.
Keywords:Expert system Fault diagnosis Spacecraft control system
