Abstract
Control of 1) the instantaneous value and 2) the mean value of the bottoms composition of a binary pilot stripping column subjected to step disturbances has been studied. The five tray column was modelled by a sixth order state-space model. This model was for control purposes augmented with one integral and one double integral state. The model was used to compute optimal feedback and feedforward control matrices. Experiments showed large fluctuations in the control. This was due to feedback of measurement errors. To get good control the feedback control matrices were multiplied by 0.3. Results from simulations and experiments are presented. It is shown in this paper that by including double integral action in a controller, it is possible to control the mean value of the bottoms composition, when the column is subjected to step disturbances.
