The Importance of Feature Processing in Deep-Learning-Based Condition Monitoring of Motors Table 1 Application of MLP in condition monitoring of motors.
Year Input data and features DL model Application Remarks 2016 Current signature MLP [47 ] Induction motor fault classification Operating frequency of the motor did not affect the accuracy of the classifier. However, increase in the accuracy was observed as severity of the fault increased 2017 Current signature and voltage signal amplitudes MLP [48 ] Induction motor fault classification The method yielded better classification results and it was computationally efficient compared to the traditional methods Current signature + MI MLP [49 ] Induction motor fault classification MI feature extraction method allowed MLP to produce promising results compared to RBF 2018 Current signature + FFT + WPT + statistical parameters MLP [50 ] Rotor broken bar fault classification Superior feature extraction allowed to detect the fault severity level even with no-load condition Current signature + CCA MLP [51 ] Induction motor fault classification The method allowed to correctly classify the faults with higher accuracy owing to reduced dimensions of the data by CCA 2019 Current signature + MI MLP [52 ] Bearing fault classification MI feature extraction method allowed to classify the bearing faults more effectively compared to conventional methods
