La estimación de estado en convertidores electrónicos de potencia es una alternativa interesante para obtener de manera indirecta algunas variables que son difíciles de medir, debido a los costos de los sensores o a las limitaciones impuestas por los ruidos de medición. Por lo tanto, en este artículo se realiza el diseño de tres estimadores de estado lineales y tres no lineales para un modelo de convertidor boost DC/DC, con el fin de verificar la conveniencia de usar solo estimadores no lineales como solución al problema de estimación de la corriente del convertidor. Adicionalmente, se prueba mediante simulación el comportamiento de estos estimadores en el software Matlab.
The state estimation in power electronic converters is an interesting alternative to obtain indirectly some variables that are difficult to measure, due to sensor costs or limitations imposed by measurement noise. Therefore, in this paper we design three linear and three nonlinear state estimators for a DC/DC boost converter model, in order to verify the convenience of using only nonlinear estimators as a solution to the converter current estimation problem. Additionally, the behavior of these estimators is tested by simulation in Matlab software.
