Optimum control is often not at the "hilltop", but at the intersection of constraints. When these constraints shift with changes in operation, a self-adaptive control scheme is required. Summary--Optimum operation of processes is often not at the "top of the hill", but at the intersection of constr
## Decoupling Control of a Distillation Column Luyben (1 ) recently discussed the use of linear decoupling control for a binary distillation column. An ideal decoupling and a simplified decoupling approach were presented. A signal flow graph analysis is presented here to show how these two methods
A frequency domain approach is used to compare the nominal performance and robustness of dual-composition distillation column control tuned according to Ziegler-Nichols (ZN) and Biggest Log Modulus Tuning (BLT) for three binary distillation columns. The scope of this paper is to examine whether ZN a
