Control of the Wood and Berry Distillation Column Using Simulink

The control of both bottom and distillate compositions is achieved by using conventional two point feedback control (WoodandBerry1) and non-interacting control (WoodandBerry2). Because of coupling, conventional control has a poorer performance when compared to the non interacting control system. Feed is regarded as a perturbation that is properly rejected by the non interacting control system. Transfer functions are taken from the book of Jean-Pierre Corriou (Commande des Procédés, Génie des Procédés de l?Ecole de Nancy, 1996) or in R. K. WOOD and M. W. BERRY, Terminal composition control of a binary distillation column, Chemical Engineering Science, 1973, Vol. 28, pp. 1707-1717.
