Resumo Inglês:
In this paper a multivariable control system for the heat exchanger of a real plant is proposed; using pi direct synthesis controllers and simplified type decouplers. In addition, the measured, controlled and manipulated variables of the units that constitute this plant and that interact are analyzed, so as not to cause conflicts between them. The cascade control configuration is chosen for the control of air temperature, which is the main function of the study plant. The results obtained at simulation scale demonstrated the effectiveness of the proposal.
Resumo Espanhol:
En este trabajo se propone un sistema de control multivariable para el intercambiador de calor de una planta real; usando controladores PI de Síntesis Directa y desacopladores de tipo Simplificado. Además, se analizan las variables medidas, controladas y manipuladas, de unidades que constituyen dicha planta y que interactúan, para no provocar conflictos entre estas. Se elige la configuración de control cascada para el control de la temperatura del aire, que es la función principal de la planta objeto de estudio. Los resultados obtenidos a escala de simulación demostraron la efectividad de la propuesta.
