Controle vetorial de campo orientado indireto em motores de indução trifásicos

Abstract

This paper aims to propose the indirect vector control oriented field to drive and control a three-phase induction motor with a PI controller in speed loop. Intended to control the direct axis current loops and quadrature thereby controlling the speed of an induction motor. First they are addressed induction motor concepts, mathematical modeling of MIT and vector control. It was carried out the test on empty and locked rotor of the machine in question, to raise the MIT parameters. Then it was made the calculations of the PI for the speed loop, in order to improve vector control. It was made the vector control’s simulation using the Matlab software, and finally the system stability was analyzed, with the application of loads, variations references, reversing direction at MIT and the empty condition.
