A systematic simulation study of dual composition control of distillation has been carried out in order to compare different decoupling strategies and contrast them with well-tuned SISO-controllers. Two column models are studied. One describes the experimental pilot plant used by Wood and Berry (1973) and the other the experimental pilot plant investigated by Luyben and Vinante (1972). A better control quality-compared to the control quality obtained by SISO-control-may be achieved if suitably chosen decoupling elements are introduced. The best control quality does not, however, necessarily correspond to the best decoupling. In the studied systems, where the controllers of the decoupled systems have been tuned according to the Ziegler-Nichols settings for the effective process transfer functions, there is no incentive to use two decouplers (two-way decoupling): the same or better control quality is obtained with the simpler scheme utilizing only one decoupler (one-way decoupling). Actually, for the Luyben and Vinante system SISO-control is superior to two-way decoupling, whereas one-way decoupling is superior to SISO-control. |
