CONTROL VECTORIAL DE LA VELOCIDAD DE UNA MÁQUINA SÍNCRONA DE IMANES PERMANENTES

Abstract

This thesis addresses the design and experimental validation of a Permanent Magnet Synchronous Motor (PMSM) drive. This project was sponsored by the Instituto de Ciencia y Tecnología del Distrito Federal (ICyTDF) under the grant awarded to the research project “Supercapacitores para Ahorro de Energía en Transporte Eléctrico” (Record Number PIC508- 50). The motor drive designed is intended to be used in the traction system of an electric vehicle. The whole system performance was simulated and assessed in Matlab/Simulink. Two different control topologies were simulated; position sensored and position sensorless control. A permanent-magnet position estimator was programmed for the sensorless control. Experimental validation was carried out in the Power Electronics Laboratory. The experimental test rig is comprised of two 10-hp Permanent Magnet Synchronous Motors, a Freescale DSP, a 1200V-70A voltage source inverter and a 10-hp electrodynamometer. Experimental results of the position sensored PMSM drive correlate well with the simulation results. Although experimental results of the closed loop speed-sensorless control were not obtained, experimental results of the speed estimation also tie well with the simulation results.
