贴近度对模糊诊断矩阵的实时修正应用研究

Application of Approximation Value to Revise Diagnosis Matrix in Fuzzy Diagnosis Process

能否正确地建立故障征兆与故障原因之间的从属关系直接决定了模糊逻辑诊断的成功与否,诊断矩阵中各个元素的取值与实际情况的符合程度直接影响到故障诊断的准确性。因此,在确立隶属函数之后,诊断矩阵与实际情况的符合程度是准确模糊诊断的关键。提出了利用贴近度,实时加权修正诊断矩阵的方法。

The fuzzy logic diagnosis success directly relies on the relation between fault indication and reason,in the diagnosis matrix each element value and the actual situation conforms to the degree directly affects the fault diagnosis accuracy. Therefore, after the establishment of subordination function, the diagnosis matrix and the actual situation conforms to the degree is the accurate fuzzy diagnosis key. This paper proposed the method that uses approximation value, real-time weighting revising diagnosis matrix.
