| 摘 要： | 为了对航天器热控系统进行及时、准确的故障诊断,文章提出了一种故障诊断策略。该策略是基于热控系统数学模型建立故障诊断数据库;然后利用专家知识扩展故障诊断数据库来实现故障诊断;最后,由基于规则的分布式故障诊断专家系统给出故障决策。

| Abstract: | For the purpose of diagnosing the faults exactly and timely of spacecraft thermal control system,the distributed model-based fault diagnosis strategy is put forward.First step of the method is to set up math model of thermal control system and store the results of computation into the computer fault database;second is to extend the database with thermal control system experts'knowledge to diagnose system faults;at last the fault decision is made from the rule-based distributed fault diagnosis system. |
