An application of nonlinear feedback theory to the control of a binary distillation column is presented. The nonlinear control structure proposed allows the output of the process to be decoupled from external disturbances while it follows, asymptotically, a given trajectory. The internal stability o

Terminal composition control of a pilot scale binary distillation column operated under the control of an IBM 1800 digital computer has been studied for disturbances in feed flow rate. Conventional two point control, whereby the overhead composition is controlled by reflux flow rate and bottom compo
Conditions are found for severe interaction to exist in a binary distillation column between the temperature, or composition and pressure control loops and between the top and bottom temperature, or composition, control loops of the column. Sunmnu~--Conditions are found in this paper for interactio
