Resumen
En el desarrollo de este trabajo se analiza el empleo de un modelo matemático fenomenológico del proceso discontinuo de cocción de masas cocidas de primera para la optimización y análisis de alternativas de control automático de dicho proceso, haciendo uso de la simulación computarizada.
Se abordan las modificaciones y procedimientos que fueron necesarios acometer para adaptar el modelo fenomenológico desarrollado en trabajos anteriores con vista a que pudiera satisfacer los objetivos de optimizar y analizar alternativas de control automático del proceso, teniendo en cuenta los enfoques novedosos de la teoría de control optimizante que se emplea en la industria de procesos a nivel internacional.
La aplicación del estudio de optimización permitió obtener el rango apropiado de operación en tachos de primera para el que se garantizó adecuados índices de calidad del proceso de cristalización, así como la aplicación de dos de los enfoques de la teoría de control optimizante: el Real Time Optimization y la Self- Optimization, los cuales permitieron seleccionar 4 esquemas de control que a través de los mismos se puede implementar la alternativa de operación óptima resultante del estudio de optimización realizado.
In the development of this work the employment of a phenomenological mathematical model of the discontinuous process of cooking of cooked masses is analyzed of first for the optimization and analysis of alternative of automatic control of this process, making use of the on-line simulation. The modifications and procedures are approached that were necessary to attack to adapt the phenomenological model developed in works previous with view to that could satisfy the objectives of to optimize and to analyze alternative of automatic control of the process, keeping in mind the novel focuses of the theory of optimization control that it is used in the industry of processes at international level. The application of the study of optimization allowed to obtain the appropriate range of operation in vacuum pan of first for the one that was guaranteed appropriate indexes of quality of the crystallization process, as well as the application of two of the focuses of the theory of optimization control: the Real Time Optimization and the Self-Optimization, which allowed to select 4 control outlines that through the same ones you can implement the alternative of operation good resultant of the carried out study of optimization.
