Model based temperature control of an exothermic semi-batch reactor

摘要

A model based temperature controller of an exothermic semi-batch reactor developed for Kemira Fine Chemicals Kokkola plant is presented. The controller is based on generic model control (GMC) introduced by Lee and Sullivan and further developed for reactor temperature control by Cott and Macchietto. Generic model control uses a dynamic model describing reactor-jacket cooling and heating system with reaction heat estimation based on temperature measurements. A simulation model of the reactor cooling and heating system was constructed using Simulink program to study the controller performance. Both simulation and practical results of GMC-based controller are presented.
