When designing the decoupling control system of a multi-component distillation column by using state variable feedback, the number of state variables to be fedback increases according to the number of components.<BR>To overcome the above short-coming, it is proposed in this paper to design the decoupling control system with a pseudo binary model. It was found that the pseudo binary model obtained from only two key-components does not give a satisfactory result for the decoupling control system design. Then a new pseudo binary model was derived by providing the direction of the composition change around the steady-state condition.<BR>It is confirmed that the decoupling control system designed by use of this pseudo binary model has almost the same performance as that designed by use of the multi-component model.
