Elementary Decoupling control of composition in binary distillation columns

Abstract

Elemenatary nonlinear decoupling (END) is a model based control algorithm which intends to decouple and linearize a nonlinear multivariable process in order to achieve better control than can be obtained by conventional decentralized linear feedback control. The application of END to the composition control of a theoretical binary distillation column illustrates that the achievable quality is very high.
