In this paper the implementation and experimental validation of a high-gain reconfigurable observer for estimating the molar composition and temperature in a distillation column with a binary mixture is presented. The observer is composed by a simplified distillation column model and the error calculation and correction of this mathematical model. The main idea of the observer is the continuous reconfiguration of the observer gain in order to reduce the estimation error at every moment, thus achieving a faster convergence of the observer to the actual response of the system. The aim of this work is to verify the functionality of this observer by its online experimental validation in a distillation pilot plant process.
