In both cases of increasing and decreasing dead time, the control scheme goes unstable. In Fig. 9, the dead time starts increasing, and the controller is able to maintain stable operation until an undetermined disturbance occurs at about 135 minutes. The prediction step is shorter than optimal, and the disturbance induces cyclic behavior which increases to saturation. In Fig. 10, the control loop manifests unstable tendencies by the end of 26 D.

Bay j0rgensen Instituttet for Kemiteknik, Danmarks Tekniske H0jskole, 2800 Lyngby, Denmark Abstract. A MIMO self tuning controller (MIMOSC) with an explicit model structure is applied to control a fixed bed chemical reactor with recirculation of unconverted reactants. The dynamic behaviour of recycle reactors is more complex than that of reactors without recycle, due to the feedback introduced by the recirculation.
