Abstract

In this paper a method for designing a decoupled controlled system with regulators to maintain constant terminal compositions in a binary distillation column is proposed. In particular, it is found that good decoupling control can be obtained by this proposed method even if the system parameters that affect decoupling control should change. In this method the remaining freedom of pole assignment is used to make the control system insensitive to parameter changes and the values of the determinable poles are selected to be smaller than the dominant poles.
