Remote power control strategy based on virtual flux approach for the grid tied power converters [PDF]

, 2018
The control of active and reactive power for the Renewable Energy Sources (RES) based power plants are very important. The injection of active and reactive power to the grid is normally controlled at the Point of Common Connection (PCC) where this point ...

Vision‐Guided Surgical Navigation Using Computer Vision for Dynamic Intraoperative Imaging Updates

International Forum of Allergy &Rhinology, Volume 16, Issue 1, Page 5-15, January 2026.
ABSTRACT Background Residual disease after endoscopic sinus surgery (ESS) contributes to poor outcomes and revision surgery. Image‐guided surgery systems cannot dynamically reflect intraoperative changes. We propose a sensorless, video‐based method for intraoperative CT updating using neural radiance fields (NeRF), a deep learning algorithm used to ...

Methods of resistance estimation in permanent magnet synchronous motors for real-time thermal management [PDF]

, 2010
Real-time thermal management of electrical ma- chines relies on sufficiently accurate indicators of internal tem- perature. One indicator of temperature in a permanent-magnet synchronous motor (PMSM) is the stator winding resistance.

Speed Sensor Fault Tolerant PMSM Machines: From Position-Sensorless to Sensorless Control

IEEE Transactions on Industry Applications, 2019
New sensorless observers (i.e., from stator currents/voltages measurements only), to be included into a simple observer-based sensorless control for the tracking of non-definitely zero speed references in nonsalient-pole surface permanent magnet synchronous machines (PMSMs), are proposed. They are obtained through a “minimum distance” modification from

An Adaptation Mechanism of Model Reference Adaptive System Based on Variable Structure Control for Online Parameter Estimation of IPMSM

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
ABSTRACT This study introduces stator currents‐based model reference adaptive system (MRAS) estimators that employ variable structured control (VSC) in the adaptation mechanism to enable the online estimation of stator resistance and permanent magnet (PM) flux in interior permanent magnet synchronous motors (IPMSMs).

High-frequency issues using rotating voltage injections intended for position self-sensing [PDF]

, 2013
The rotor position is required in many control schemes in electrical drives. Replacing position sensors by machine self-sensing estimators increases reliability and reduces cost. Solutions based on tracking magnetic anisotropies through the monitoring of

An Adaptive Velocity‐Sensorless Control Strategy of Multi‐Locomotive Freight Trains Using a Non‐Recursive Control and High‐Gain Observer

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes an adaptive‐velocity sensorless control strategy for freight trains using multiple electric locomotives operating under external disturbances. The control strategy is designed based on a non‐recursive control framework with a time‐varying control parameter. The elimination of velocity sensors is achieved through a high‐gain observer

Experimental verification of an angle-sensorless control scheme for bearingless permanent magnet machines

Mechanical Engineering Journal, 2017
Bearingless machines are used for a variety of applications with demand for low mechanical loss, low wear and low contamination. These machines use contact-free magnetic suspension to levitate the rotor. The control of the machine requires precise radial
