MSc. Oscar Ivan Higuera Martínez.
PhD. Juan Mauricio Salamanca.

Abstract: This paper presents the design of a controller with discrete sliding mode controls applied to a Buck power converter; the converter model in space states and the robust control law design are presented. The controller is proved in a converter model with real parameters simulated in Matlab/Simulink and the results obtained are showed considering different model parameters disturbances and changes, The analysis of results are presented.

Keywords: Discrete, sliding mode, robust, power converter, variable structure.

Resumen: Este artículo presenta el diseño de un controlador basado en modos deslizantes discreto aplicado a un convertidor de potencia Buck, se presenta el modelo del convertidor en espacio de estados y el diseño de la ley de control robusta. El controlador se prueba en un modelo del convertidor con parámetros reales simulado en Matlab/Simulink y se muestran las gráficas de los resultados obtenidos frente a diferentes perturbaciones y cambios en los parámetros del modelo, realizando un análisis de los resultados reportados.
