Cost-Effective Predictive Flux Control for a Sensorless Doubly Fed Induction Generator

open access: yesIEEE Access, 2019
The paper introduces a cost effective predictive flux control (PFC) approach for a sensorless doubly fed induction generator (DFIG). The base operation of the proposed PFC depends on controlling the rotor flux (α-β) components using a cost ...

Robust Sensorless Model-Predictive Torque Flux Control for High-Performance Induction Motor Drives

open access: yesMathematics, 2021
This paper introduces a novel sensorless model-predictive torque-flux control (MPTFC) for two-level inverter-fed induction motor (IM) drives to overcome the high torque ripples issue, which is evidently presented in model-predictive torque control (MPTC).

Sensorless MPPT Algorithms for PV Systems in Partially Shaded Scenarios

open access: yesEletrônica de Potência
This manuscript presents current sensorless algorithms for maximum power point tracking (MPPT) in partially shaded photovoltaic (PV) systems. The necessity of a current sensor is eliminated with the use of mathematical modeling of the power electronics ...

Comparison of Intraoperative Doppler Flow Measurements and Algorithmic Flow Estimations in Patients Undergoing Durable Left Ventricular Assist Device Implantation

open access: yesArtificial Organs, EarlyView.
Direct intraoperative HeartMate 3 LVAD flow measurements using an ultrasonic probe revealed consistently higher values by approximately 0.5 L/min compared to device‐estimated flows. This discrepancy remained stable across pump speed settings, highlighting the importance of distinguishing measured from estimated flow in HeartMate 3 patients.

AI‐Based Exergaming as a Digital Assessment Tool for Post‐Stroke Upper‐Limb Function: Protocol for a Feasibility Study

open access: yesPhysiotherapy Research International, Volume 31, Issue 3, July 2026.
ABSTRACT Background and Purpose Accurate assessment of upper limb motor function is critical for guiding effective rehabilitation strategies in stroke survivors. The Fugl‐Meyer Assessment for Upper Extremity (FMA‐UE) is a widely used clinical tool, yet it is time‐consuming and subject to inter‐patient variability.

Position-sensorless control of permanent-magnet-assisted synchronous reluctance motor

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.

Research on Displacement Sensorless Control for Bearingless Synchronous Reluctance Motor Based on the Whale Optimization Algorithm–Elman Neural Network

open access: yesActuators
The unique structure of bearingless motors requires extra displacement sensors to monitor rotor movement, unlike conventional synchronous motors. However, this requirement inevitably escalates the cost and size of the motor. To address these issues, this
