Control de posición del rotor de un motor de inducción por el método de control de campo orientado (FOC)

Abstract

This document presents the design, implementation, and evaluation of a Field-Oriented Control (FOC) system applied to the rotor position control of a Siemens 1LA7 070-4YC60 induction machine. The main objective was to develop a control strategy that decouples flux and torque, ensuring a precise and stable dynamic response to variations in load and reference. The project was structured in phases that included machine modeling, compensator design, simulations in a MATLAB/Simulink environment, and experimental implementation using hardware provided by the MEM research group. The experimental results demonstrate robust performance of the FOC system: the current loop showed response times of less than 25 ms without overshoot; the speed loop, although initially affected by noise, was stabilized through digital filtering; and the position loop achieved steady-state stability, although overshoot occurred during transients due to the lack of integral action. Furthermore, an energy conversion efficiency exceeding 78% was achieved at full load. This work contributes to academic training by integrating theory, simulation, and practice, and lays the groundwork for future developments in advanced control of electrical machines in industrial and educational contexts.
