Modelo matemático de una máquina asíncrona en estado dinámico y simulación en matlab

Abstract

This document describes the mathematical modeling of an asynchronous induction machine working as a motor, through the use of mathematical software Matlab® and Simulink. This software allowed to solve the differential equations that govern the electrical behavior of the machine in a fast and efficient way, which considered the variables defined in the development.

The variables of the differential equations were obtained from the real electrical diagram of the asynchronous induction machine, which allowed the exact calculation of the behavior of the machine in its regimes, permanent and transient, with or without load.

It was demonstrated through the mathematical model that the theoretical, experimental and simulated calculations correspond to the behavior of the asynchronous induction motor, which showed the graphs of the start current of the stator and the rotor. Thus, the prediction of the state of the current variables of the equipment according to its operation was possible.

The most important function of this mathematical modeling was the practical demonstration of the behavior of the starting current of the rotor, which allowed the comparative analysis of the calculated and experimental values, as well as the development and verification of the different methods that were applied.
