Contribuição ao controle sensorless de motores síncronos de ímãs permanentes
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2019-12-05)
This thesis presents contributions to sensorless control for permanent magnet synchronous
motors. A maximum torque per ampere strategy is used to generate the current
control reference in synchronous reference frame. ...
Contribuições ao acionamento e controle sensorless aplicado ao motor de indução bifásico assimétrico
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2012-05-11)
This doctoral thesis presents the development of sensorless methods aiming the rotor
speed control of asymmetrical two-phase induction motors. Initially, the machine mathematical
model is presented. From the machine model, ...
Estimation of Electrical Machine Speed Using Sensorless Technology and Neural Networks
(Ieee, 2008-01-01)
The use of sensorless technologies is an increasing tendency on industrial drivers for electrical machines. The estimation of electrical and mechanical parameters involved with the electrical machine control is used very ...
Control strategies for power smoothing using a flywheel driven by a sensorless vector-controlled induction machine operating in a wide speed range
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS, 2004)
Nonlinear observer-based control for PMSG wind turbine
(Pergamon-Elsevier Science Ltd, 2016-10)
This paper introduces a mechanical sensorless control strategy to be used in variable speed wind energy conversion systems based on permanent magnet synchronous generators. The goal of the control strategy is to track the ...
High-performance sensorless nonlinear power control of a flywheel energy storage system
(Pergamon-Elsevier Science Ltd, 2009-07)
The flywheel energy storage systems (FESS) can be used to store and release energy in high power pulsed systems. Based on the use of a homopolar synchronous machine in a FESS, a high performance modelbased power flow control ...
