浅谈铁磁谐振故障诊断系统的研究

On Research of Ferromagnetic Resonance Fault Diagnosis System

在研究铁磁谐振故障特点以及产生铁磁谐振故障条件的基础上分析了PT饱和铁磁谐振故障诊断的因果关系,创建了一种树状知识模型,并针对故障现象的不确定性采用模糊产生式知识表示方法,并利用专家系统技术对实际运行中发生的铁磁谐振故障进行诊断。

In this paper, the characteristics of ferromagnetic resonance and factors resulting in ferromagnetic resonance are an- alyzed.Based on that, the causality of PT saturation resulting in ferromagnetic resonance is discussed and arborescent knowledge model established,and ferromagnetic resonance fault that takes place during the operational process is diagnosed through expert system by adopting fuzzy epsilon-production knowledge expression based on uncertainty of fault symptom.
