The application of Hilbert–Huang transform energy spectrum in brushless direct current motor vibration signals monitoring of unmanned aerial vehicle

open access: yesAdvances in Mechanical Engineering, 2016
Due to the characteristics of structure, brushless direct current motor has a long lifetime, which makes it more difficult to obtain failure data. Accordingly, valid degeneration characteristics are required in life prediction.

Comparative analysis of series fault arc detection methods

open access: yesGong-kuang zidonghua, 2017
For uncertainty of line fault location, current series fault arc detection methods are mainly based on current signal analysis. By comparing current waveforms before and after series arc fault under different loads, characteristics and regularities of ...

Hilbert-Huang Transform for ERP detection [PDF]

open access: yes, 2012
Při vyhodnocování ERP experimentů je naprosto nezbytné přesně určit amplitudu a~latenci jednotlivých ERP komponent. Protože je EEG signál kvazi-stacionární, je nezbytné pro jeho analýzu použít časově-frekvenční metody, jako je waveletová transformace ...

Resolving Nonstationary Spectral Information in Wind Speed Time Series Using the Hilbert-Huang Transform [PDF]

open access: yes, 2010
This work is motivated by the observation that large-amplitude wind fluctuations on temporal scales of 1–10 h present challenges for the power management of large offshore wind farms.

Estimation of Teager energy using the Hilbert–Huang transform

open access: yesIET Signal Processing, 2015
A new method to estimate the Teager energy (TE) is presented here which uses an instantaneous energy expression and the Hilbert–Huang transform (HHT). The energy expression depends on the square of the instantaneous amplitude and digital frequency of the signal.

Cognitive Radio Sensing Using Hilbert Huang Transform

open access: yesWireless Engineering and Technology, 2010
Vast segments of the frequency spectrum are reserved for primary (licensed) users. These legacy users often un-der-utilize their reserved spectrum thus causing bandwidth waste. The unlicensed (secondary) users can take advantage of this fact and exploit the spectral holes (vacant spectrum segments). Since spectrum occupancy is transient in nature it is

Aeroelastic Flight Data Analysis with the Hilbert-Huang Algorithm [PDF]

open access: yes, 2005
This paper investigates the utility of the Hilbert-Huang transform for the analysis of aeroelastic flight data. It is well known that the classical Hilbert transform can be used for time-frequency analysis of functions or signals.
