Design of an Adaptive Flux Observer for Sensorless Switched Reluctance Motors Using Lyapunov Theory

Advances in Electrical and Computer Engineering, 2020
This paper proposes an adaptive flux observer for a sensorless switched reluctance motor. The observer adaptive gains are designed using the Lyapunov theory to guarantee both the accuracy and stability of the sensorless control of a switched reluctance

Estimation of Saturation of Permanent-Magnet Synchronous Motors Through an Energy-Based Model [PDF]

, 2011
We propose a parametric model of the saturated Permanent-Magnet Synchronous Motor (PMSM) together with an estimation method of the magnetic parameters. The model is based on an energy function which simply encompasses the saturation effects. Injection of

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 ...

Investigation of Motor Current Signature Analysis in Detecting Unbalanced Motor Windings of an Induction Motor with Sensorless Vector Control Drive [PDF]

, 2015
Maintaining the efficiency of AC motors in site equipment is important, given the increasing cost of energy. Reduction of motor efficiency from baseline manufacturer data can go undetected until total failure of the equipment is experienced.

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).

Sensorless control of deep-sea ROVs PMSMs excited by matrix converters [PDF]

, 2005
The paper reports the development of model-based sensorless control methodologies for driving PMSMs using matrix converters. In particular, experimental results show that observer-based state-estimation techniques normally employed for sensorless control

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

Mitigation of cross-saturation effects in resonance-based sensorless switched reluctance drives [PDF]

, 2010
The stator and rotor yoke in a switched reluctance motor form magnetic circuit parts that are typically shared by different phases. If these parts saturate due to the excitation of one phase, this will lead to a change of the magnetic characteristics of ...
