Kyryk V. Regulation and stabilization of varying parameters of electrotechnological systems using fuzzy logic

Object of research is the electrotechnological systems with fuzzy regulation and with stabilization of variable electrical and technological parameters. The aim of research: development of the theory of regulation and stabilization of parameters of electrotechnological installations with non-stationary processes on the basis of development of new methods of fuzzy control and synthesis of nonlinear systems of shaping of solution of control of the power device. Methods of a research: the theory of fuzzy logic, fuzzy simulation, imitative and physical simulation. Theoretical and practical results and innovations: new methods of formation of nonlinearity's character the defuzzification method of inference was developed, for the first time a way of definition of an optimal amount of indistinct variables and criterion of their limitation was developed; the voltage regulator for the electric furnace was developed. A subject and degree of application: new methods of formation of nonlinearity's character areused in electrothermal systems Ltd"Terebov" and recommended to usage in Institute of common power engineering of Ukrainian National Academy of Sciences. Efficiency of application: heightening of a regulation quality, power efficiency and productivity. Sphere of usage: electrothermal and electromechanical systems.
