飞行器故障诊断专家系统中的知识联想

Knowledge Association in Expert System for Fault Diagnosis of Certain Spacecraft

在建立某飞行器故障诊断专家系统时，针对诊断知识的特点，提出了一种用相似匹配进行知识联想的方法．实际系统在可视化工程环境（ＨＰＶＥＥ）下开发完成，应用于某飞行器故障诊断时，能通过联想产生实用的诊断规则，对缺少诊断知识的故障症状进行尝试性推理．

In accordance with the characters of the fault diagnosis, this paper introduced a method of using matching with comparability in knowledge association when building an expert system (ES) for fault diagnosis of certain spacecraft. It described the theoretical basis, realization process and working environment (HP VEE) of such knowledge association. Finally the ES can produce some new rules via knowledge association to reason those faults we have no knowledge to diagnose.
