Interfacial Chemistry Behind Damage Monitoring in Glass Fiber‐Reinforced Composites: Attempts and Perspectives

Polymer Composites, Volume 47, Issue 4, Page 2925-2954, 20 February 2026.
Role of the modifications at the interface in glass fiber reinforced composites for damage monitoring. ABSTRACT Glass Fiber Reinforced Polymers (GFRPs) are widely used in structural applications but degrade over time due to internal damage. Structural Health Monitoring (SHM) enables early damage detection, improving reliability and reducing maintenance

The Detection of Shaft Misalignments using Motor Current Signals from a Sensorless Variable Speed Drive

, 2014
Shaft misalignments are common problems in rotating machines which cause additional dynamic and static loads, and vibrations in the system, leading to early damages and energy loss.

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 ...

Sensorless control of the synchronous reluctance motor [PDF]

Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 1994
In this paper a sensorless closed-loop speed control for the synchronous reluctance motor is presented. The sensorless control is based on the torque vector control algorithm. It has been implemented using a high-speed digital processor DSP96002. Experimental results for a 120 W axially-laminated synchronous reluctance motor are presented and compared ...

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).

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

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
