In this article, the analysis of trends in the development of modern theory and technology of automatic control of technical objects is carried out.The authors described the transfer function of the control object. he substantiation of the methodology for the synthesis of fuzzy control algorithms is given in accordance with the required criteria for the functioning of automatic systems. It is shown that in order to stabilize the operation of systems, fuzzy P – controllers must form a nonlinear law of object control. Five axiomatic requirements for the response surface of a fuzzy static controller have been developed. The algorithm for the synthesis of fuzzy P-type controllers when implemented was developed using Matlab. Expert solutions of the initial state of the fuzzy controller are given. The linguistic variables of the input action are generated. Models of a system with a classical PID – controller and a fuzzy P – type controller are built in the Simulink environment. The results of four experiments are given in which a purposeful change in the parameters of the accessory functions of the input linguistic variable and a change in the rule base made it possible to obtain the specified performance indicators of the automatic system. The experiments were carried out using an intelligent gradient model-experimental method. Static characteristic, transient response and quality indicators are obtained as a result of simulation. The results of the work are presented in the form of graphs of the studied characteristics, formed on the basis of calculations using Matlab.
