Diseño e implementación de un sistema de gestión de energía de una batería para el control de un motor trifásico de 4 polos como aplicación para vehículos eléctricos

Abstract

The present study introduce the controls system’s design of a thriphase motor, which allows to manage the energy of a battery in a efficient way through soft starting processes, nominal running and regenerative braking, since the project is focused in the implementation of this system in electric vehicles. The control is done by mean of the use of a Direct Torque Control (DTC) that enable to hold the torque in a independent manner, this is possible thanks to a change of a reference’s axis thriphase to a reference’s two-phase. For doing the convertion of the coordinate’s system the Park’s transform is used because it contemplate different motor variables, got from sensors and some estimations. In addition, it is proposed a new fuzzy control system’s scheme, which allow simplify or reduce the complexity of traditional concressors without changes in its effectiveness, from boolean logic.
