## Fault diagnosis method based on extension rule-based reasoning

Funds: Weapons and Equipment Pre-Research Foundation of the PLA General Equipment Department;Special Foundation for "Taishan Scholars" Construction Project
• 摘要: 针对产生式规则推理方法存在的推理效率低、知识获取困难以及难以用于多故障诊断等问题,研究基于可拓规则推理的故障诊断方法。首先将基元理论和产生式规则相结合,得到可拓规则的基元表示;然后给出可拓规则匹配度计算公式,并提出按前件基元类型和属性数据类型不同对可拓规则进行分层匹配,对所有匹配成功的可拓规则,提出先删减再排序的冲突消解策略,在算法分析中讨论可拓规则推理的时间复杂度;最后通过应用案例说明可拓规则表示、匹配、推理和冲突消解的全过程,结果表明该方法适用于机载设备的多故障诊断。
