Abstract: 

Distillation column control has been a challenging problem for numerous research activities. Review of past research reveals that among the advanced control methods applied to this system, little attention has been paid to feedback linearization, even in absolutely theoretical cases. This is due to the singularity of the system in steady-state, which invalidates the linearized control law. In this paper, to overcome this problem, a new idea has been suggested that is based on approximate feedback linearization. Based on this idea, an approximate non-linear model has been introduced for the distillation column which can exactly be linearized while reserving the structural properties of the basic system. The control law is derived from the approximate model and then applied to the basic system. The introduced error between the approximate and basic systems is then fed back by two single loop PID controllers to improve the performance of the system. Further, in these approach disturbances due to changes of feed flow and composition has been perfectly decoupled using the disturbance decoupling theory.
