Designing control system with entropic modeling

Contributions of entropic modeling to the performance of reactive process control have been investigated. Modeling has been developed based on mass, energy and entropy balances and thermodynamic relations, resulting in a model for the entropy production rate. Using the conventional optimization technique, a minimum for the entropy production rate was found when a given relationship between the temperatures of the inlet stream and of the reaction is satisfied for a particular residence time in the reactor. A new class of nonlinear controller is proposed by means of introducing entropic models into the classical algorithms designed from a synthesis of the reference system. The results indicate that such a controller yields a superior performance when compared with classical feedback control strategies.
