Effective Variable‐Speed Bearing Fault Diagnosis From Motor Current Signals Using Kurtosis‐Guided VMD and Multi‐Branch Convolutional Neural Network

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This study presents a novel deep learning‐based fault classification framework utilising Variational Mode Decomposition (VMD) for adaptive feature extraction and a Multi‐branch Convolutional Neural Network (M1D‐CNN) architecture for classification. The VMD hyperparameters were optimised based on kurtosis to ensure the extraction of the most informative

Nonlinear Controller Design and its Optimization for Real‐Time Implementation for a Servo Motor Drive

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes an EXP‐PI controller as a practical alternative to the conventional PI controller, integrating EXP functions on the error and its rate within the control structure. The controller is optimized using five recent intelligent algorithms, with SFS providing the most effective parameter tuning.

A Study on the Down‐Scaling of Transient Drive Cycles for Experimental Analyses With Laboratory Based Small Motors

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
A new down‐scaling method for the laboratory based analysis of transient drive cycles is proposed and analysed. In contrast to the typically used dimensionless per unit steady‐state operating‐point based scaling methods, this approach also considers information on the cycles' transient characteristics in the scaling process. ABSTRACT Standardised drive

Speed‐Sensorless Model‐Free Predictive Torque Control for Induction Motor Drive

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
A speed‐sensorless MF‐PTC based on EKF is proposed for a 2L‐VSI‐fed IM drive to reduce the overall cost and complexity of the drive system. The rotor speed is estimated using the EKF. The instant rotor flux is also estimated using the EKF based on the rotor current model of IM, whereas a direct machine model is employed in general to estimate the rotor
