Estimación Robusta de los Estados de un Tren de Tres Reactores Químicos Exotérmicos

Resumen: Se estudia el problema de diseñar un estimador para inferir en línea cinco estados (tres concentraciones y dos temperaturas) de un tren de tres reactores químicos con reciclo a partir de mediciones de: (i) entradas exógenas de flujo volumétrico y temperatura y (ii) temperatura de uno de los reactores. El objetivo es obtener un diseño con construcción y sintonización sistemática con un compromiso adecuado entre velocidad de convergencia, robustez y carga computacional en línea. Mediante un enfoque constructivo se obtiene: (i) un criterio de convergencia robusta, (ii) sintonización simple, (ii) criterio para ubicar el sensor, y (iii) con mucho menos ecuaciones, funcionamiento similar al del filtro extendido de Kalman (FEK).
