摘要:

摘要:为提高凝汽器故障诊断的准确性,将模糊理论运用到凝汽器故障诊断技术中,提出了一种新的隶属函数,建立了凝汽器故障诊断模型,合理运用阀值理论避免了病态征兆集引起的误判断,最后通过对故障实例的诊断证明了此诊断模型的高效分离性和准确性。

Abstract:

Abstract:In order to improve the fault diagnosis accuracy of condenser,the fuzzy theory was introduced to the fault diagnosis technology and a new improved membership function was proposed in this paper.Then a fault diagnosis model of condenser was built,which using the valve value theory reasonably to avoid misjudgment that caused by diseased symptoms.After that,a diagnosis to the fault example verified the high
separability and accuracy of the fault diagnosis model.
