Abstract
A new approach to control-system design is proposed: integrated synthesis of the control subsystem and its object. Such synthesis is based on models of the objects and control algorithms, with the identification of permissible model-algorithm combinations. Physical-mathematical simulation is effectively employed in synthesis. As an illustration of this approach, control systems are synthesized for oxygen converters in steel production. It is found that the models of smelting must be expanded by the introduction of factors that affect the converter parameters in the course of oxygen injection. Various designs for the control systems are appraised. The best is found to be the system based on an integrated model of the object (with ongoing variation in the converter parameters) and an integrated control algorithm.
