The study has revealed that further prospects for the efficiency growth in using mechanized technologies for cultivating grain crops in Siberia are offered by soil cultivation, which consumes from 30 to 40 percent of all energy costs. The research purpose is to justify the methodological principles of automatic controlling an energy-intensive process of tillage in agricultural technologies of grain cultivation. Used were the methods of statistical analysis and synthesis of technical control means. There has been developed a system of automatic mode regulation belonging to the class of automatic adaptive systems with programmable positional control of input data and ensures that the machine-and-tractor unit is in the optimal range of energy modes. The minimum of dynamic error has been accepted as the quality criterion of the positional control system. To measure it, use has been made of Mahalanobis-type metric taking account of the Hamming distance. The operation of a machine-and-tractor unit has been controlled by power and kinematic regulation of the engine operating modes on tractors with a hydraulic gearbox and a gas-turbocharged engine. The effect was directed on the fuel pump rail or the fuel control lever, the gear shift lever, and the hydraulic system levers. The study has revealed a random nature of the change in traction resistance of the machine-and-tractor unit caused by the heterogeneity of the soil cover. It has been determined that this leads
to increased energy intensity, as well as insufficient performance of built-in information systems indicating the current energy modes of operation of the machine-and-tractor unit operation. To control and regulate the soil heterogeneity by its hardness, a new technical solution has been proposed. The authors have proved that the developed and tested theoretical foundations and technical means of automatic control of energy-intensive technological processes of tillage ensure the required quality indicators.
