Projeto e análise de observadores adaptativos aplicados ao controle sensorless de máquinas síncronas de ímãs permanentes
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2018-08-06)
This master dissertation presents contributions to the study, development, and design
of adaptive observers applied to the estimation of rotor speed of permanentes magnet
synchronous machines. The rst proposed technique ...
Estimating vocal fold contact pressure from raw laryngeal high-speed videoendoscopy using a Hertz contact model
(MDPI AG, 2019)
The development of trauma-induced lesions of the vocal folds (VFs) has been linked to a high collision pressure on the VF surface. However, there are no direct methods for the clinical assessment of VF collision, thus ...
Análise e proposição de estratégias de estimação e controle de velocidade para motores de indução trifásicos
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2016-05-31)
This study presents a proposal of speed servomechanisms without the use of mechanical sensors (sensorless) using induction motors. A comparison is performed and propose techniques for pet rotor speed, analyzing performance ...
A sensorless speed controller for induction motors
(Planta Piloto de Ingeniería Química, 2009-02-23)
This paper presents a novel sensorless strategy for controlling speed in AC drives containing induction motors. The controller uses field oriented control strategy calculated with estimated rotor flux and speed. These ...
