Optimal control for technological process with distributed state variables and with a large dead times in the object is discussed. Very important problem for creating control system with using the object model in the control loop are considered. It has been shown that heat flux calorimetry is an effective experimental technique for the development of an exothermic (or endothermic) chemical process model based upon the process kinetic model and hydrodynamic media inside object. Successful application of this approach for the creation of mathematical models and their further use in the corresponding control systems has been demonstrated for two different important industrial processes – sintering process in the preparation of cement clinker in the tubular rotating kiln and modification process of epoxy resins with butanediol-1,4 for further synthesis of epoxy-urethane polymers with improved physical and mechanical properties. The mathematical model of a technological object makes it possible to specify the optimal operating mode for each of the considered processes and implement the optimal control conditions.
