Prokhorenko A. Scientific principles of diesel management systems that include electrohydraulic fuel delivery system

Processes in control systems of feeding of fuel of the diesel drives equipped with electrohydraulic fuel equipment. Working out of scientific principles of creation of effective ways of regulation of feeding of fuel and rational algorithms of automatic control in diesel engines for heightening of their technological level by equipment by electrohydraulic fuel equipment. For integration of the differential equations which describe dynamic systems, in the thesis are used: a method of performances, D'Alamber's method and a Runge-Kutt's method. For identification of numerical mathematical models and holding of program optimisation the method of research of space of parametres on the basis of Sable grids is used. For calculation of response of dynamic systems on an input signal which any way varies in time, the Duhamel integral method is used. The linearization method is used for set of equationses in fractional derivatives. The technique of synthesis of algorithm of operation of the electronic block of control of a diesel engine with electrohydraulic accumulative fuel system is developed. Modern methodical approaches to synthesis of an electronic regulator of a rotational speed. Improvement of a construction of the operating valve for electrohydraulic fuel equipment of a diesel engine is offered. It is developed and программно the complex of mathematical models of hydromechanical devices of fuel equipment of diesel engines with electronic control is realised. For the first time directive-adaptivny principle of construction of algorithm for the electronic block of control by fuel feeding in a diesel engine with accumulative fuel equipment in which value of a base matrix are adjusted according to observations of a complete set of transmitters of the drive is offered and scientifically justified mixed. Have received development methods of the theory of systems of autocontrol and control explosion engine in sphere of application of electronic regulators for the diesel engines equipped with electrohydraulic fuel equipment. For the first time for simulation of transients of a diesel engine it is offered to use own shapes of free oscillations autocontrol system of a high order and a Duhamel integral. Have received the further development mathematical models and methods of the dynamic analysis of aggregates of fuel equipment of diesel engines. Results are introduced in practice of research and development and issledovatelsko-design operations in KP "KhKBD" (Kharkov), are transmitted to use at projection and manufacture of electrohydraulic fuel equipment to the enterprises: RPE "Т.О.Р." (Kharkov), the state enterprise "the Factory it. Malyshev" (Kharkov), and also are used at holding of educational process and scientific researches on chair of explosion engines NTU "KhPI". An engine building.
