Fault Classification Method of Motor Based on Variational Modal Decomposition and CNN-BiGRU-Attention Neural Network
For solving the problem of low accuracy of fault classification results of motor
a kind of fault classification method for motor based on variational mode decomposition (VMD) and CNN-BiGRU-Attention neural network model is proposed. Firstly
the motor data of Case Western Reserve University is preprocessed
and then the complex motor signal is decomposed into multiple intrinsic mode function (IMF) components by VMD method and the fault feature vector of motor is constructed. Finally
the feature training CNN-BiGRU-Attention neural network model is set up
and the specific types of faults of motor are diagnosed based on the iterative training of the model. The experimental results show that after the application of the proposed diagnosis method
the number fault classification errors of motor is less and the accuracy of test set is up to 97%. The method has high robustness and accuracy.
