Resumen
Este trabajo se aborda el problema de diseño y control de una planta perteneciente a una etapa clave del proceso de obtención del azúcar de caña como es la clarificación. Se presenta una aproximación novedosa al problema de diseño y control simultáneo del proceso considerando tanto la controlabilidad de estado (basada en métricas de controlabilidad práctica) como la controlabilidad de salida (basada en índices dinámicos de control), tomando como ejemplo el caso de la torre sulfitadora. Esta propuesta se traduce en un problema de optimización no lineal donde se imponen restricciones sobre las condiciones de operación de la planta, las medidas de controlabilidad de estado y algunos índices de desempeño a lazo cerrado, mientras se minimizan los costos de inversión, operación y control. El problema de optimización se resolvió satisfactoriamente empleando algoritmos genéticos.
