基于证据理论的电机故障诊断方法研究

The Diagnosis Method of the Electric Machines Fault Based on Evidential Theory

在DS证据理论的基础上 ,结合模糊集合论 ,给出了多传感器数据融合一般化方法 ,并将其应用于电机故障诊断 .通过数据融合诊断结果与单传感器诊断结果的比较 。

A data fusion general method based on D S evidential theory and fuzzy logical theory is presented that is used in the electric machines fault diagnosis. In the example by comparing the experiment results based on separate original data and fused data respectively, it is shown that the latter is more accurate than the former in the fault recognition.
