Abstract
The dynamics of a fed-batch reactor was studied using the detailed fir st principle model of the system. The conditions of reaction runaway, the typical sources of hazardous operation in fed-batch techniques are determined. Considering these conditions a model-based control scheme is proposed to ensure robustness. When the stability criterion predic ts that the range of operation is safe the cooling is set to its maxim um and the temperature is controlled by the reactant feed. Otherwise t he reactant feed is stopped and the flow rate of the cooling medium is the control variable.
