Diseño e implementación de un sistema de control vectorial por orientación de campo con realimentación de velocidad para un motor trifásico de inducción

Abstract

The present work seeks to implement a vector control system by field orientation for the Machine Control Laboratory, with which it is possible to magnetize the machine properly, by including in the control loop a regulator for the component associated with the magnetic flux, so it is possible to operate at low speeds. In a first instance, the initialization process is carried out to determine the magnetic flux angle of the rotor. Subsequently, the PI regulators are implemented for the currents in the reference system dq, so it is possible to have a system invariant in time, thus simplifying the complex mathematical model of an AC machine. Finally, a user interface is designed, which allows the monitoring of the three-phase currents, the currents in the αβ and dq systems, the magnetic fluxes of the stator and the rotor and the torque of the machine. In this way we have a module that facilitates the understanding of vector control theory by field orientation, since it is possible to monitor the variables in the different stages of the process.
