摘要
针对某天然气压气站的大型离心压缩机故障诊断的要求,提出一种基于模糊理论的故障诊断模型。该模型基于征兆对于故障的肯定及否定程度,提出修正模糊关系矩阵,能够适应复杂故障的诊断。实践证明这种诊断模型应用在压缩机故障诊断上是可行的。
A mathematic model of fault diagnosis based on the fuzzy theory was established for the large centrifugal compressors in natural gas station.According to the positive and negative effect of symptoms to faults,the revised fuzzy relation matrix was introduced to suit for complex fault diagnosis.The proposed model was proved to be practicable on fault diagnosis for centrifugal compressor.
