Position-sensorless control of permanent-magnet-assisted synchronous reluctance motor [PDF]

open access: yes, 2003
The sensorless control of permanent-magnet-assisted synchronous reluctance (PMASR) motors is investigated, in order to conjugate the advantages of the sensorless control with full exploitation of the allowed operating area, for a given inverter.

A Neural Network‐Based Self‐Sensing Embedded Position Control System for Shape Memory Alloy Wire Actuators

open access: yesAdvanced Intelligent Systems, EarlyView.
Shape memory alloy wires exhibit thermally induced phase changes that generate actuation strain and resistance variations enabling self‐sensing. However, hysteretic electromechanical behavior complicates accurate state estimation. This paper presents an artificial in‐based self‐sensing method to reconstruct SMA actuator position in real time, achieving

Sensorless position control of permanent magnet motors with pulsating current injection and compensation of motor end-effects [PDF]

open access: yes, 2011
The sensorless position control of permanent-magnet motors is successfully implemented by superimposing a high-frequency voltage signal on the voltage reference or adding a high-frequency current signal to the current reference.

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

open access: yesPolymer 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

Cross-Saturation Effects in IPM Motors and Related Impact on Sensorless Control [PDF]

open access: yes, 2006
Permanent-magnet-assisted synchronous reluctance motors are well suited to zero-speed sensorless control because of their inherently salient behavior. However, the cross-saturation effect can lead to large errors on the position estimate, which is based ...

Performance Improvement of PMSG‐Based Wind Energy Systems via Sensorless FS‐Predictive Current Control With MRAS and MPPT‐OTC Integration

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a hybrid sensorless control strategy for a permanent magnet synchronous generator (PMSG)‐based wind energy conversion system (WECS). The approach integrates finite‐set predictive current control (FS‐PCC), a model reference adaptive system (MRAS) estimator and an optimal torque control maximum power point tracking (MPPT‐OTC) method ...
