Journal ArticleDOI
Non-Stationary Motor Fault Detection Using Recent Quadratic Time-Frequency Representations
TL;DR: In this article, the Zhao-Atlas-Marks distribution is used to enhance nonstationary fault diagnostics in electric motors, which can be implemented on a digital signal processing platform.
Journal ArticleDOI
Analytic-Wavelet-Ridge-Based Detection of Dynamic Eccentricity in Brushless Direct Current (BLDC) Motors Functioning Under Dynamic Operating Conditions
TL;DR: Experimental results are provided to show that the proposed method works over a wide speed range of motor operation and provides an effective and robust way of detecting rotor faults such as dynamic eccentricity in BLDC motors.
Journal ArticleDOI
Detection of Rotor Faults in Brushless DC Motors Operating Under Nonstationary Conditions
TL;DR: In this paper, two novel methods using windowed Fourier ridges and Wigner-Ville-based distributions are proposed for the detection of rotor faults in brushless dc motors operating under continuous nonstationarity.
Journal ArticleDOI
Feedforward Transient Compensation Control for DFIG Wind Turbines During Both Balanced and Unbalanced Grid Disturbances
TL;DR: In this article, a feedforward transient compensation (FFTC) control scheme with proportional integral-resonant current regulators is proposed to enhance the lowvoltage ride through (LVRT) capability of doubly fed induction generators (DFIGs) during both balanced and unbalanced grid faults.
Journal ArticleDOI
Optimum Space Vector Computation Technique for Direct Power Control
TL;DR: In this article, an optimized direct power control (ODPC) algorithm is proposed to provide a closed-form formula for the converter space-vector voltage, which, based on Lagrange operators for the optimum trajectory, provides the commanded complex apparent power.
