Lesovoy I. Sinthesis radiotecnical automatic control systems on the basis of fuzzy logic.

In the thesis the questions of construction fuzzy logic digital controllers are considered. A functional diagram of a fuzzy controller and the principle of the operation in a radiotecnical automatic control systems are briefly described. The decision-making process based on fuzzy logic, which is the basis of the operation of fuzzy controllers is described. Fuzzy controllers in radio automatic control sysnems with nonlinear objects are synthesized. The problems of optimization of their basic parameters (ranges of variatin of linguistic variables, shape and mambership function parameters of linguistic quantities) are explained important for design of digital fuzzy controllers by minimizing the square-law perfomance criterion for the porpose of deriving optimum transient processes in radio automatic control systems with fuzzy controllers
