Abstract :
A distillation column on a pilot plant scale is input-output linearized via asymptotically exact I/O-linearization. A model consisting of differential and algebraic equations (DAE) is used to derive an observer and the feedback law. The outputs to be controlled are functions of algebraic state variables. Therefore the theory of I/O-linearization is extended here to explicit DAE-systems of index 1 with implicit algebraic equations. The practical application demonstrates the excellent performance of asymptotically exact I/O-linearization
