The article presents a new methodology for creating information technology for the design of a combined system for stabilizing the flow of bread mass at the entrance to the combine thresher. The characteristic features of such a methodology are outlined. This allows the design of process control systems on the combine, taking into account external influences that are stochastic in nature. The stages of creation of information technology for the synthesis of the optimal combined stabilization system with feedback on the deviation of the bread weight from the average value and correction for changes in yield are substantiated. The article substantiates the composition and determines the content of operations of the new information technology of designing a combined system of stabilization of the flow of bread mass at the entrance to the thresher of the combine. The new technology has several distinctive features. First, its introduction allows to obtain differential equations of the combine harvester, which take into account the dynamic properties and design features of hydraulic transmissions operating in the mode of constant load change. Secondly, it allows you to design process control systems on the combine, designed for external influences that are stochastic in nature. Third, the new technology allows the synthesis of optimal combined stabilization systems under the conditions of two multidimensional independent sources of disturbance at the input and output of the stabilization object.
