EMD与Elman神经网络在风机故障诊断中的应用

The Applicatio n of EMD and Elman Neutral Network in Fault Diagnosis of Fan

采用经验模式分解(EMD)进行信号分解获取IMF后构建特征向量,采用Elman神经网络进行识别,识别率高,具有可行性。

The EMD is adopted to carry out the signals decomposition and construct feature vectors after obtaining IMF.And the Elman neutral network is used to identify them,which has the feature of high identification and is feasible.
