Gender differences in attitudes towards driving and demand for private insurance: Evidence from middle class drivers
(Elsevier Sci Ltd, 2017-05)
This article examines the existence of associations between the gender of the driver, their risk behavior when driving motor vehicles and their inclination to acquire automobile insurance. To conduct this investigation a ...
Mechanical Sensorless Speed Control of Permanent Magnet Motors Driving an Unknown Load
(Institute of Electrical and Electronics Engineers, 2006-04)
A new sensorless scheme for high-performance speed control of permanent-magnet ac motors (PMACMs) driving an unknown load is proposed. This scheme uses an extended nonlinear reduced-order observer to estimate the induced ...

Controle de velocidade sensorless de motores brushless DC submetidos a variações periódicas de carga
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2011-07-21)
This master thesis presents a sensorless speed control drive of Brushless DC motors
used in reciprocating compressors. These compressors cause periodic load torque
variations on the motor, consequently mechanical vibrations ...
Neural approach for speed estimation in induction motors
(Ieee Computer Soc, 2007-01-01)
The use of sensorless technologies is an increasing tendency on industrial drives for electrical machines. The estimation of electrical and mechanical parameters involved with the electrical machine control is used very ...

Mechanical-sensorless induction motor drive based only on DC-Link measurements
(The Institution of Engineering and Technology, 2006-11)
Sensor count reduction for high-performance induction motor (IM) drives is considered. A novel strategy to compute the three phase currents, based on a single current sensor and an adaptive observer, is proposed. The ...
