MODELING OF THE FLOW ADAPTIVE SYSTEM FOR CONTROLLING THE SOIL TILLAGE

Abstract

It is well known that one of the significant disadvantages of the development of modern technological processes is the use of aspects of thinking associated with the use of already used design positions. From a practical point of view, there is no single optimal solution for tillage in agriculture. The methodology for solving complex, multipolar problems of quality and efficiency of technology must take into account a significant number of factors and be presented in an accessible form for the response of the working bodies of tillage machines. Precision tillage has great potential. The result of tillage operations can be improved depending on the optimal solution of construction working bodies and technological parameters of cultivating, which, in addition, can be adapted to the tillage technology depending on the local agro-climatic conditions. The article presents the results of the synthesis of the system of adaptive control of soil cultivation by creating a complex technological system with modeling of the structural-matrix schemes and on-stream technological influences of working bodies of machines and external agro-climatic conditions on the agrophysical state of the soil. The research methods are methods of analysis of structural schemes of technological process control systems; system-analog modeling of tillage control systems; structural analysis and synthesis of technological changes in agrophysical indicators of soil tillage. The main results are the structural diagram of the on-stream adaptive control system of the tillage unit for the requirements of precise agriculture; matrix diagram of the imaging and generalized system of equations of on-stream adaptive control of working bodies of tillage machines; system-analog model of the machine-tractor unit with the adaptive control system of working bodies.
