Three classification algorithms, SVM, K-nearest neighbor (KNN), and integration, and 17 different classifiers provided in the MATLAB Classification Learner Toolbox were used to evaluate the performance and applicability of different classifiers to induction motor fault diagnosis. Accessibility These time series were acquired by SpectraQuests Mechanical Failure Simulator (MFS) aligned with the sensors on the balanced vibration (ABVT). Original sources: (a) white Gaussian noise; (b) 40 Hz cosine waveform; (c) 60 Hz sine waveform; (d) 100 Hz sin waveform; (e) 10 Hz triangular waveform. Their research method used selected features, which were passed to SVM and the ANN to identify and further classify various bearing defects. The InitializeMethod (the method of initializing the center frequency) was peaks, and peaks were used to initialize the center frequency to the peak position of the signal in the frequency domain. To evaluate the method proposed in the text more comprehensively, it was compared with the current mainstream methods with the same test set from both qualitative and quantitative aspects. In this research, two signal processing techniques, matching pursuit and discrete wavelet transform, were selected for feature extraction. See ResNet101_Weights below for more details, and possible values. The untrained model does As does Rough f. Total params: 234,355,586 Trainable params: 210,767,874 Non-trainable params: 23,587,712. A series network is a neural network for deep learning with layers arranged one after the other. Resnets are made by stacking these residual blocks together. Hilbert transformation of VMD analysis of vibration data of horizontal misalignment motor failure. ResNet101_Weights.IMAGENET1K_V1.transforms, ResNet101_Weights.IMAGENET1K_V2.transforms, Deep Residual Learning for Image Recognition. We first verified the performance and effectiveness of VMD. The research was based on the theoretical basis of the electric drive, and the researchers developed a simulation model to simulate the normal state with all single switches and faults after a short circuit for verification. ResNet network converges faster compared to the plain counterpart of it. In this study, all data in the six categories were converted into images of the Hilbert spectrum. In the discussion of the results, Table 3 is also added to show the network structure of the three methods, Table 4 shows the comparison of the parameters of the three methods, and Table 5 describes the comparison of the characteristics of the three methods with additional explanations. Learn about PyTorchs features and capabilities. Qi et al. The fault diagnosis method based on vibration signal processing is currently widely used, known as empirical mode decomposition [33]. This research has significant value for the maintenance and development of motors. AlexNet achieved 57% and 80.3% as its top-1 and top-5 accuracy respectively. official website and that any information you provide is encrypted Although the obtained Hilbert marginal spectra were different, the five frequencies were very close. The research project of Murphey et al. ResNet101_Weights below for Before Pretrained ResNet-101 convolutional neural network, returned as a DAGNetwork object. The type of the AlexNet approach is a series. ResNet50_vd_ssld further improves the accuracy of top-1 of the ImageNet-1k validation set by using stronger teachers and more data, reaching 82.39%, refreshing the . ResNet101 (DnnImageModelSelector, IHostEnvironment, String, String) Returns an estimator chain with the two corresponding models (a preprocessing one and a main one) required for the ResNet pipeline. You can use classify to Then, the effective decomposition components of a given signal and the optimal solution of the variational problem were obtained. Research data are used to compare the performance of the three models through a data set released by the Federal University of Rio de Janeiro (UFRJ). At present, typical mechatronic products such as electric vehicles, CNC machine tools, and AC servo drives are developing in the direction of digitization, miniaturization, complexity, and high precision, presenting new challenges for fault monitoring and diagnosis. This function requires the Deep Learning Toolbox Model for ResNet-101 Network support package. Arguments. Practical Evaluation Metrics for a Semantic Search Bot, from tensorflow.keras.applications import ResNet101, from tensorflow.keras.applications import ResNet152, https://github.com/KhuyenLE-maths/A-quick-overview-of-ResNet-models/blob/main/A_quick_overview_of_ResNet_models.ipynb. Since neural network training usually uses the backpropagation algorithm for chain product derivation, when the shallow parameters are updated, as the information propagates forward, the gradient of the shallow layer tends to zero. 50-layer ResNet: Each 2-layer block is replaced in the 34-layer net with this 3-layer bottleneck block, resulting in a 50-layer ResNet (see above table). The error classification is 1 each for overhang bearing, underhang bearing, and vertical misalignment. ResNet-101 is a convolutional neural network that is 101 layers deep. The number of images for training and verification is shown in Table 3. Electric vehicles have become an important new type of green transportation with the characteristics of being clean and environmentally friendly and providing the efficient use of multiple energy sources. Vibration data of horizontal misalignment motor failure. The shortcut connections perform identitymapping, and their outputs are added to the outputs of the stacked layers. The series contains six different kinds of test data: normal function, unbalanced fault, horizontal and vertical misalignment fault, and internal and external bearing malfunction. Based on your location, we recommend that you select: . The row at the bottom of the graph shows the percentage of correct and incorrect classifications of all examples belonging to each category. These five components were transferred to the Hilbert spectrum, as shown in Figure 5. The network has an image input size of 224-by-224. When misclassified to 1 for underhang bearing, the error is 6.7%, the vertical misalignment classification accuracy rate is 93.3%, and for misclassification of 1 for horizontal misalignment, the error is 6.7%. weights: . This will cause the gradient to become increasingly small, making the network difficult to learn. [10] proposed a machine learning technique applied to data analysis and fault diagnosis in a reciprocating compressor system. By clicking or navigating, you agree to allow our usage of cookies.

s5(t) represents a triangular wave of 10 Hz. https://creativecommons.org/licenses/by/4.0/. There are 18 layers present in its architecture. The proposed method does not require a large amount of prior knowledge of fault diagnosis, does not need to denoise the signal, simplifies the feature extraction process of motor fault diagnosis, and has a high fault diagnosis accuracy rate. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. L2Regularization is 0.0000500, Momentum is 0.96, GradientThreshold is Inf, GradientThresholdMethod is l2norm, the SequenceLength is the longest, SequencePaddingValue is 0, and ExecutionEnvironment is gpu. resnet101 function to coder.loadDeepLearningNetwork (GPU Coder).

To evaluate the model, use the image classification recipes from the library. Accelerating the pace of engineering and science. If the initial value of the input is large, the gradient needs to be multiplied by a sigmoid derivative when backpropagation. As a result, the network has learned rich feature representations for a wide Also includes the renaming ColumnsCopyingTransforms required to be able to use arbitrary input and output column names. Their research proved the rationality and effectiveness of the scheme in conflict and fault diagnosis management.

(a) ResNet101-C alone can be used to classify lung CT images into normal and pneumonia and therefore detect COVID-19. Tra V., Kim J., Khan S.A., Kim J.-M. [16] developed an integrated fault diagnosis algorithm for the motor sensor of an electric vehicle independently driven by the wheel. Through the construction and solution of the constrained variational model, the signal was decoupled into several IMFs with limited bandwidth, and the signal was adaptively decomposed according to the frequency domain characteristics of the signal.
