Journal ArticleDOI
Cascaded H-Bridge Multilevel Inverter System Fault Diagnosis Using a PCA and Multiclass Relevance Vector Machine Approach
TL;DR: A fault diagnosis strategy based on the principle component analysis and the multiclass relevance vector machine (PCA-mRVM) that not only achieves higher model sparsity and shorter diagnosis time, but also provides probabilistic outputs for every class membership.
Journal ArticleDOI
Fault diagnosis method based on FFT-RPCA-SVM for Cascaded-Multilevel Inverter
TL;DR: A new fault diagnosis method, based on Fast Fourier Transform (FFT), Relative Principle Component Analysis (RPCA) and Support Vector Machine (SVM), is proposed for H-bridge multilevel inverter to guarantee stable operation of system.
Journal ArticleDOI
An imbalance fault detection method based on data normalization and EMD for marine current turbines.
TL;DR: The experiments show that the proposed method is robust against turbulence through comparing the different fault severities and the different turbulence intensities.
Journal ArticleDOI
An adaptive confidence limit for periodic non-steady conditions fault detection
TL;DR: Wang et al. as mentioned in this paper proposed a fault detection method using adaptive confidence limit (ACL) in periodic non-steady conditions, which can reduce dimensionality, remove correlation, and improve the monitoring accuracy.
Journal ArticleDOI
EEMD-based notch filter for induction machine bearing faults detection
TL;DR: The achieved simulation and experimental results clearly show that the proposed approach is well suited for bearing faults detection regardless the rank of the intrinsic mode function introduced by the fault.
