成果简介	NOVELTY - Group of inventions relates to aircraft engine building and can be used in electro-hydromechanical systems for automatic control of gas turbine engines. Disclosed is a method of controlling a gas turbine engine, as well as a device for its implementation. Method of controlling the position of guide vanes of a compressor of a gas turbine engine or a fuel valve involves identification of the nonlinearity parameter of the center of the dead zone of the electrohydromechanical drive of the “dead zone” type in real time, and compensation of nonlinearity. Besides, nonlinearity parameter is additionally identified as width of non-sensitive electrohydromechanical drive of “dead zone” type in real time, wherein nonlinearity compensation providing asymptotic control stability and astatic accuracy of positioning of compressor or fuel valve guides, is carried out taking into account the conversion of the output signal of the control device taking into account the found nonlinearity parameters by the formula: where Ip is the control signal from the output of the control device; I u is control current supplied to input of electro-hydromechanical drive; N is the maximum value of the control current variation range; d = (zP + zL)/2 is the center of the dead zone of the electro-hydromechanical drive, which is identified in real time by the formula: where Y0(t) is a given position of the actuator; Y(t) is the actual position of the actuator; dt1 is the current value d at the moment of time tl; e(t) is the actuator position current error; k, g are tuning parameters depending on the engine operating mode and determining the identification unit speed; Z = zP – zL is the width of the dead zone, which is identified in real time by formula where K0 is transmission coefficient of the control object; Zo > 0 is a certain initial value of the width of the dead zone; Kz, a are tuning parameters; t is current time. USE - Aviation. ADVANTAGE - Technical result consists in provision of asymptotic stability and astatic accuracy of positioning of controlled element taking into account nonlinearity of characteristics of electro-hydromechanical units. 2 cl, 1 dwg
