Procedures for diagnosing bearing failures of induction motors based on motor current signals in published methods commonly denoise signals acquired from current sensors, then extract the typical characteristics from the denoised signals, and use a classifier to discriminate the state of bearing.

In this paper, a SVM parameter optimization method based on Adaptive Elitist Differential Evolution (AeDE-SVM) is proposed. Furthermore, AeDE-SVM is applied to diagnose roller bearing fault by using complementary ensemble empirical mode decomposition (CEEMD) and singular value decomposition (SVD) techniques.

This paper presents a new method for roller bearing fault diagnosis based on least square support vector machine (LSSVM) with parameters optimized by Backtracking Search Optimization Algorithm (BSOA), namely BSOA-LSSVM. First, roller bearing acceleration vibration signals are decomposed into functions by using Variational Mode Decomposition (VMD) method.

This paper proposes an integration of one-againstone (OAO) strategy and support vector machines (SVM) to diagnose multiple faults of steel plates. The OAO is adopted to address multi-classification tasks in the binary SVM (i.e, OAOSVMs). The performance of the proposed model is compared with that of optimization algorithm-based SVM.

Dissolved gas analysis is widely used for preventative maintenance techniques and fault diagnoses of oilimmersed power transformers. There are also various conventional methods of dissolved gas analysis for insulating oil in power transformers including methods of Doernenburg ratios, Rogers ratios and Duval’s triangle. The Bayesian techniques have been developed over many years and applied to a range of different fields including the problem of training in artificial neural networks.
