Resumo

En este artículo se presenta un modelo discreto genérico para sistemas de estructura variable. El modelo es aplicado a cualquier sistema de estructura variable de operación cíclica, como convertidores de potencia. Se asume que la frecuencia de conmutación es un múltiplo entero de la frecuencia de muestreo y se emplea retenedor de orden cero. El circuito o el sistema opera en modo cíclico con G posibles configuraciones, el modelo generado es usado en pequeña señal y baja frecuencia, y se valida usando Matlab / Simulink 2007.

Palavras-chave

sistema de estructura variable, sistema discreto, frecuencia de conmutación, muestreo de datos, convertidor de potencia, modelo
