摘要
针对故障诊断专家系统实用性与通用性的矛盾,在简要分析专家系统工作原理的基础上,提出了一种以用户为中心,基于规则表达的通用性专家知识库故障诊断方法。将规则推理?模糊决策[1]融为一体,形成一阶梯式故障推理机制;对不同的诊断对象,只要设置好必要知识表达模型,就可自行生成一专用基于规则的专家知识库故障诊断方法,并能自动输出诊断结果。
In order to overcome contradiction of practicality and generality for fault diagnosis expert system,the design of general fault diagnosis method based on user and regular characterization is presented after the expert system is introduced concisely.Rule reasoning and fuzzy decision algorithm are merged,and the step fault diagnosis method is accomplished.For different object,when necessary knowledge properties former is given,a special fault diagnosis method on regulation will be automatically produced,and the diagnosis result will be given.
