Estudo de modelo e controle vetorial orientado pelo fluxo estatórico de motor de indução trifásico para propulsão de veículos elétricos

Abstract

The speed control of three-phase induction motors is essential for the operation of electric vehicles. Therefore, the study of the machine mathematical model for the development of simpler and more effcient methods for the control of motor parameters is important for technological development and reduction in the costs of building electric vehicles. In this project, the study of the mathematical model for the analysis of the behavior of an electric induction motor was carried out and a eld oriented control strategy was developed that uses mathematical transformations and changes of reference of the measurable quantities in an induction machine and, from this strategy, a simulation was developed. The transient and permanent response of the electromagnetic fux, conjugate, speed and electric currents obtained in the simulated environment show the reaction of the model of the induction machine with the control proposed in this work, accelerating from inertia to near to the rated speed and the elimination of the disturbance caused by the insertion of the rated mechanical torque on the motor shaft. Thus, the simulation results presented validate the theoretical considerations and show the effectiveness of the proposed control strategy, enabling its use for future studies by the UFEPE-UACSA formula SAE team.
