IMPLEMENTACIÓN Y COMPARACIÓN EXPERIMENTAL DE ALGORITMOS DE CONTROL DE VELOCIDAD CON CONVERTIDORES DE POTENCIA (IMPLEMETATION AND EXPERIMENTAL COMPARISON OF SPEED REGULATION ALGORITHMS WITH POWER CONVERTERS)
Resumen
En este documento se presenta la implementación y la comparación experimental de tres algoritmos de control reportados previamente en la literatura a un sistema convertidor reductor para la regulación de velocidad de un motor de corriente directa (CD). En particular, se implementa un controlador proporcional e integral, un controlador basado en un observador y un control por técnica de inversión. Se describe la plataforma experimental desarrollada para la validación de los algoritmos. Los resultados muestran que el controlador basado en observador ofrece el mejor desempeño, destacándose por su precisión en el seguimiento de referencia y su robustez a los cambios de referencia.
Palabras Clave: Control de velocidad, convertidor reductor, motor CD, sistemas de control.
Abstract
This document presents the experimental implementation and comparison of three controllers previously reported in the literature for a buck converter system for the speed regulation of a direct current (DC) motor. In this specific case, a proportional–integral controller, an observer-based control, and an inversion of control are implemented. The experimental platform developed for the validation of the control algorithms is described. The results show that the observer-based controller offers the best performance, standing out for its precision in reference tracking and its robustness to changes in reference.
Keywords: Keywords: Buck converter, control systems, motor DC, speed control.
