Estudo de um sistema de controle sensorless para máquinas síncronas de ímãs permanentes internos

Abstract

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 accurate information on the rotor position of the machine. Obtaining parameters from sensorless techniques becomes interesting for increased robustness and reduced costs. In this sense, this work presents a study of a full-order observer for the estimation of electromotive forces and machine speed. Additionally, to validate the project, it presents a virtual hardware-in-the-loop simulation and the results obtained.
