Abstract

Off set free set point tracking is a challenging problem in distillation column control. This is
usually due to the multivariable nature of the distillation column and hence the interaction
between the loops. This study designed a model predictive controller using MATLAB and
Simulink for a Lubyen Vinate Distillation Column. The results show that the model predictive
controller performs an off set free set point tracking and disturbance rejection of about 70%.
The system has a fast settling time of 5 minutes and 3 minutes for the 17th and 4th column
respectively. This shows that the designed system has an efficient control as compared to the
response of distillation column 60 minutes and 40 minutes for the 17th and 4th column
respectively.
