Multivariable control of overhead and bottoms composition of a binary distillation column subjected to feed flow disturbances has been studied. The study has been performed using a pilot scale column, equipped with overhead and bottoms composition analyzers, operated under the control of an IBM 1800 digital computer. The column dynamic behavior, for control law calculation, was approximated by a two state variable model. Experimental results employing multivariable feedback and multivariable feedforward‐feedback control laws are presented.
