Implementación del control directo del par con inversor multinivel para un motor de inducción.

Abstract

In this work, a direct torque controller for a squirrel-cage induction motor will be implemented, low-cost programming will be carried out on a DSPic, the inverter used will be three levels and the level selector will be replaced by a neural network. seeks this project is to improve the direct control of the torque (DTC) classic in terms of reducing the harmonic distortion with which the engine is powered, because this advanced technique of motor control has the best dynamic behavior but its disadvantage lies in that the torque presents a large ripple and with it the voltage of the motor supply presents a great harmonic distortion, to have the inverter more than two levels have a greater number of vectors so the complexity of looking what should be the optimal voltage vector increases, with the neural network seeks to identify optimally what should be the voltage vector that will produce less harmonic distortion.
