Demin D. Simulatiom and optimization of control of electrosmelting processes under uncertanty conditions

Object of study: the control of electric smelting processes. The aim of the study - the development of the methodology for determining the structure and parameters of the models that describe the electric smelting processes under conditions of uncertainty, for further search of optimal control. Methods: methods experiment planning and methods of pattern recognition, optimization theory, probability theory, the theory of queuing systems, fundamentals of the theory of control. Theoretical and practical results: are based on the use of artificial orthogonalization methods for estimating the structure and parameters of the regression equations used to describe the processes of electric melting in the face of uncertainty and the construction of algorithms for optimal control at the stage of melting of the charge and termovremennoy melt processing. Scientific novelty: the development of simulation and optimization techniques of control of electrosmelting under uncertainty conditions. Degree of implementation: results implemented in Public joint-stock company "Kremenchug plant of road machines "Kredmash" (Kremenchug), Ukrainian Research Institute of foundry machinery, foundry technology and automation foundry (Kharkov), State Enterprise "Ukrainian research & technology center of metallurgy industry "Energostal" (Kharkov), "Kharkov Machine-Building Plant "Light miner" (Kharkov), Limited Liability Company Kharkiv Lifting and Transportation Equipment Plant (Kharkov). Application area: designing or upgrading process control electric melting in foundries and machine-building enterprises in the steel mills.
