Nonlinear control of a permanent magnet synchronous motor with disturbance torque estimation
(Institute of Electrical and Electronics Engineers, 2000-06)
This paper introduces a sensorless nonlinear control scheme for controlling the speed of a permanent magnet synchronous motor (PMSM) driving an unknown load torque. The states of the motor and disturbance torque are estimated ...
Position Sensorless Permanent Magnet Synchronous Machine Drives: A Review
(Institute of Electrical and Electronics Engineers, 2020-07)
Owing to the competitive advantages of cost reduction, system downsizing, and reliability enhancement, position sensorless control methods for permanent magnet synchronous machine drives have drawn increasing attention ...
Magnetic properties of Nd-Dy-Fe-B-Nb sintered magnets produced using the hydrogen decrepitation process
(Switzerland: Trans Tech Pub., 1999, 2014)
Super hybrid quadrupoles
(2012)
A new model of quadrupole composed of permanent magnetic material, coils and soft magnetic material is proposed for the new Brazilian Synchrotron Light Source (Sirius). These quadrupoles must have flexibility about 30% of ...
Adaptive full-order observer analysis and design for full-range sensorless interior permanent magnet synchronous motor drives
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2021-10-22)
This Thesis presents contributions to the study, development, analysis and design
of adaptive observers applied to the estimation of rotor position and speed of interior
permanent magnet synchronous motors (IPMSM). The ...
Study of the control structure of a small wind turbine with permanent magnet synchronous generator
(2012-12-12)
This paper presents the analysis of the two control structures used in wind generation systems with permanent magnet synchronous generators, variable speed and fixed pitch, to determine which structure is most appropriate ...
