3. Object: agricultural machines and technologies for form-ing of the set variable rates application of technological ma-terials in the system of precision agriculture.Objectives: Rising of efficiency of agricultural machines functionality in the technologies of precision agriculture by optimization of parameters and modes of functioning of the systems of dosage and of site-specific distributing of mate-rials on the area of field.Methods of investigation and apparatus: positions of sys-tems analysis, mathematical apparatus of theory of opti-mum regulation, theory of the navigation systems of mobile objects, theory of optimum evaluation.Theoretical and practical results: - the expedience of input of procedures of dynamic parame-ters authentication and adaptive adjusting of coefficients of control law of the dosaging systems of machines-realizes is grounded;- the procedures of locally quadratic approximation of data, which are acted from map-task, and also from the sensor of intensity of the job output stream of technological materi-als, which enable realization of algorithms of management with prognostication, smoothing out of noise errors of sen-sor and reduction of influencing of its inertia are offered;- a compensative method of variable rate application, which allows to reduce a level of site-specific information senes-cence and in such a matter to promote the precision of re-alization of map-task is developed;- on the base of reached scientific results the experimental pieces of fertilizer distributors for the technologies of PA are made on the OAO "Hmelnikselmash".Newness of introduced: - a method of forming of control law of metering device of machine-realizes with the algorithm of optimum tracking with prognostication is developed; - the composition of the navigation complex of MTA on the base of GSP, course-speed and inertial navigation sub-systems is grounded; - a method of adjusting of the control law of the regulative systems of metering devices for the production terms at the unforeseen changes of levels of parameters of machine tools by the use of analytical approximations and interpola-tion in space of dynamic parameters of the system is devel-oped;Level of applying: Recommendations in how to construc-tion of the high-fidelity systems of dosage and distributing of technological materials on the area of field. Experimental standards of firmware and hardware for working in the sys-tem of precision agriculture for the sowing machines and for spreaders of mineral fertilizers.Field of applying: mechanized plant-grower.
