| description | This document describes the validation of linear multivariable control designs in a heat exchanger under virtual environment using Hysys, where the interest was focused on the analysis of the different responses of MIMO system when regulatory control was done with different decouplers and without decoupler. Three types of decoupling were used: Steady-State Simplified, Simplified and Generalized. The values of the set-points were 60 °C for the flow temperature at the outlet of the tubes, and 41 °C for the flow temperature at the outlet of the shell; the manipulated variables were the flows into the tubes and the shell, because percentages of opening the corresponding valves. PI controllers were tuned by IMC design and used to regulate the temperatures. By comparing the outcomes, it´s evident that Simplified Decoupling is the best to reduce the effect of the disturbance by coupling. |

El presente artículo describe la validación de los diseños de control multivariable lineal en un intercambiador de calor bajo ambiente virtual usando Hysys, cuyo interés se centró en analizar las diferentes respuestas del sistema MIMO cuando se realizó el control regulatorio con diferentes desacopladores y sin desacoplador. Se usaron tres tipos de desacopladores: Simplificado de Estado Estacionario, Simplificado y Generalizado. Los valores de las consignas fueron 60 °C para la temperatura del caudal a la salida de los tubos, y 41 °C para la temperatura del caudal a la salida de la carcasa; las variables manipuladas fueron los caudales de entrada a los tubos y la carcasa, gracias a los porcentajes de apertura de las válvulas correspondientes. Se emplearon controladores PI que fueron sintonizados con la aplicación del diseño IMC. De los resultados se pudo apreciar que el desacople simplificado fue el que más disminuyó el efecto del acoplamiento.
