REALISTIC MODEL-BASED PREDICTIVE AND ADAPTIVE-CONTROL OF BATCH REACTOR

This paper presents an original approach which makes use of a realisti c thermal model for adaptive predictive control and supervision of a s emibatch jacketed reactor. The first part is devoted to the developmen t of an adaptive controller based on a realistic model established by thermal balances on the reactor and its jacket. As a first interest, a n on-line deterministic estimator of the heat generated during the rea ction is developed. In a second part a realistic model is used for mod el supported supervision to prevent temperature overshoot, especially in the case of industrial reactors, the temperature control being ensu red by the adaptive controller.
