摘要
以某极轨对地观测卫星为背景 ,分析了姿态控制系统中单机部件出现故障时 ,系统将会出现的状态变化情况 ,找出故障部件的判定方法 ;提出采用产生式规则与框架的混合知识表示结构 ,描述姿控系统及其故障特点 ;并提出了系统发生故障时 ,故障部件的自主隔离、备份部件的自主切换和系统重构方案。
This article analyzes the status change in the attitude control system when faults appear based on one polar orbit satellite, and provides a method to decide faulty component. It also puts forward a mixed knowledge represention which uses generating rules and frames to describe attitude control system and fault characteristics and the approach for automatic seperation of faulty component, automatic switch of spare parts and system replacement. Simulation test verifies the system's fearibility.
