Minimum Deviation Control of a Binary Distillation Column Using Reduced Order Dynamic Matrix

[摘要] References(17)Cited-By(6)Minimum deviation control, an advanced technique using a reduced-order dynamic matrix, has been proposed and its performance is investigated through simulation and experiment. Performances of the existing dynamic matrix control technique and the proposed technique are compared in a simulation study by changing set points of top and bottom temperatures and feed flow rate. A control experiment is also conducted with a pilot-scale binary distillation column using the proposed control method.From the simulation result, it is found that the new technique is better than dynamic matrix control in overall performance. The experimental test also shows that the proposed control strategy is suitable for practical application and is better than the existing technique.
