Fault diagnosis of rotating machinery based on the statistical parameters of wavelet packet paving and a generic support vector regressive classifier
TL;DR: A new intelligent fault diagnosis scheme based on the extraction of statistical parameters from the paving of a wavelet packet transform (WPT), a distance evaluation technique (DET) and a support vector regression (SVR)-based generic multi-class solver is proposed.
Journal ArticleDOI
Multiscale noise tuning of stochastic resonance for enhanced fault diagnosis in rotating machines
TL;DR: In this paper, an improved stochastic resonance (SR) approach with parameter tuning for identifying the defect-induced rotating machine faults is proposed. But the proposed approach requires small parameters, which is not suited for rotating machine fault diagnosis as the defect induced fault characteristic frequency is usually much higher than 1 Hz.
Journal ArticleDOI
Subspace-based gearbox condition monitoring by kernel principal component analysis
TL;DR: Experimental analysis with a fatigue test of an automobile transmission gearbox shows that the KPCA features outperform PCA features in terms of clustering capability, and both the two K PCA-based subspace methods can be effectively applied to gearbox condition monitoring.
Journal ArticleDOI
Effects of underdamped step-varying second-order stochastic resonance for weak signal detection
TL;DR: An underdamped step-varying second-order SR (USSSR) method is proposed to further improve the output signal-to-noise ratio (SNR) and has three distinct merits as good anti-noises capability in detecting weak signal being submerged in heavy background noise.
Journal ArticleDOI
Machine condition monitoring using principal component representations
TL;DR: In this paper, the low-dimensional principal component (PC) representations from the statistical features of the measured signals to characterize and hence, monitor machine conditions are automatically extracted using the principal component analysis (PCA) technique from the time and frequency-domains statistical features.
