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 ...

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 ...

The effects of asymmetrical magnet faults on the rotor of permanent magnet synchronous machines (PMSM) are analyzed in the present work. Two different stator winding configurations, series and parallel connected windings, ...

This master thesis presents the development of an experimental setup to drive and control of permanent magnet synchronous motors with external rotor. The main characteristics of these electric motors are related to their ...

This paper presents the study and development of a sensorless control method for the Permanent Magnet Synchronous Motor (PMSM) based on the estimation of back Electromotive Force (back-EMF). A vector control method is ...

This paper presents a study of state observers for the control of permanent magnet synchronous electric machines. In order to ensure the correct functioning of the machine, control techniques employed in PMSMs require ...

This paper presents a method for electromagnetic torque ripple and copper losses reduction in (non-sinusoidal or trapezoidal) surface-mount permanent magnet synchronous machines (SM-PMSM). The method is based on an extension ...

Line-start permanent magnet motor (LSPMM) is a very attractive alternative to replace induction motors due to its very high efficiency and constant speed operation with load variations. However, designing this kind of ...
