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.

Suppression of DC Winding Current Harmonics in Wound‐Field Machines Under PWM Excitation by Using Active Voltage Injection and LC Low‐Pass Filters

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
In this paper, the LC low‐pass filter is designed and connected in parallel with the DC winding of the MFMWF machine to suppress the high‐frequency sideband harmonics in the DC winding current for the first time. The suppression effect is validated by experiments.

Transfer Function Model of a Brushless Exciter

Journal of King Saud University - Engineering Sciences, 1997
Brushless exciters are widely used in power stations to furnish the excitation current for the main alternators. These exciters are maintenance free and possess high gain and forcing margin. Transfer function models available for such exciters are somewhat complicated and deal with few variables.

Sensorless Standstill Diagnosis of Rotating Diode Open‐Circuit Faults in WFSSG via Current‐Vector Modulus

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
Open‐circuit faults in rotating diode rectifiers (RDRs) disrupt excitation current in WFSSG systems. A modified rotor current vector modulus (CVM) with harmonic distortion analysis enables accurate fault detection even at standstill, without rotor position sensors.

A Lumped Parameter Thermal Model for Double Stator Wound‐Excited Magnetic Field Modulation Machine

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a lumped parameter thermal model (LPTM) for the DS‐WMFM machine. A detailed method for calculating and constructing the LPTM for the DS‐WMFM machine is given in this paper. To validate the prediction accuracy of the established LPTM, three experimental tests including DC test, rated condition test, and variable condition test are ...

Adaptive Heuristic Direct Torque Control for High‐Phase Electronic Pole‐Changing Induction Machines: Hardware‐in‐the‐Loop and Experimental Evaluation

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
ABSTRACT High‐phase electronic pole‐changing induction machines (ePCIMs) offer inherent redundancy and extended torque‐speed capability, making them suitable for high‐power traction applications such as electric buses and heavy‐duty electric vehicles. However, pole‐changing transitions produce severe transient currents that degrade dynamic performance ...

Real‐Time Implementation of Finite Control Set Model Predictive Control for BLDC Motors With Dynamic Speed References on ESP32

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper investigates the application of Finite Control Set Model Predictive Control (FCS‐MPC) for Brushless DC (BLDC) motor speed regulation under dynamic references, including sinusoidal, square, triangular, and sawtooth signals. A novel cost function is introduced to evaluate switching frequency effects, and the influence of different weighting ...
