Borisova1, I.N. Nurutdinova2, V.P. Dimitrov3 1,2,3 Don State Technical University, Rostov-on-Don, Russian Federation Подход к решению задачи по выбору значений регулируемых параметров комбайна на основе нечеткого моделирования Л. <...> Ростов-на-Дону, Российская Федерация A problem of selecting the controlled parameter values of the combine harvester work tools is considered. <...> Models describing the harvesting quality factor dependencies of the external agents are analyzed. <...> The need of a new approach to modeling the technological adjustment process of the harvester in the field which takes into account the fuzzy information on the environmental factors, its approximate character, as well as an expert method of generating information, is justified. <...> To describe the environmental factors and the performance indices, linguistic variables are introduced, their membership functions are developed, and production rules are formulated. <...> The fuzzy inference process is illustrated by an example of selecting the beater rate speed. <...> A knowledgebase and an inference engine that form the expert system basis are created. <...> A practical implementation of the developed model is the creation of the software for the automated problem solution of the technological adjustment of the harvester in the field. <...> Проанализированы модели, описывающие зависимости показателей качества уборки от внешних факторов, и обоснована необходимость нового подхода к моделированию процесса технологической регулировки комбайна в полевых условиях, учитывающего нечёткость информации о факторах внешней среды, её приближённый характер, а также экспертный способ формирования информации. <...> Ключевые слова: зерноуборочный комбайн, технологическая регулировка, нечеткие знания, лингвистическая переменная, экспертная система. <...> The implementation of the potentialities included in the design of the combine harvester, achievement of high quality performance of harvesting and productivity are only possible with a correct technological adjustment of working units and observance of operating rules. <...> Complex and changing environmental conditions grain harvesters operate under require the operator to find optimal solutions promptly. <...> To develop optimal algorithms of technological adjustment, it is necessary to know accurate values of environmental factors <...>
