Abstract :
Dual composition control of binary distillation columns is proposed and solved based on observer design and an elementary state elimination procedure. A particular observer allows us to recover the unmeasured feed composition, which is used in the controller design in order to maintain desired compositions. The method is an alternative against disturbance decoupling
