Performance Improvement of PMSG‐Based Wind Energy Systems via Sensorless FS‐Predictive Current Control With MRAS and MPPT‐OTC Integration

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a hybrid sensorless control strategy for a permanent magnet synchronous generator (PMSG)‐based wind energy conversion system (WECS). The approach integrates finite‐set predictive current control (FS‐PCC), a model reference adaptive system (MRAS) estimator and an optimal torque control maximum power point tracking (MPPT‐OTC) method ...

Partial Discharge Pattern Recognition Based on Time‐Frequency Multi‐Scale Residual Attention Network

open access: yesIET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
A time‐frequency multi‐scale residual attention network (TFMRAnet) was designed to analyze partial discharge (PD) signals. The network comprises an adaptive denoising network based on multi‐scale residual attention, a frequency‐domain recognition network, and a decision fusion module based on Dempster‐Shafer (D‐S) evidence theory.
