Polyvoda O. Optimization of operational control of moisture supply in irrigation system

Object - the automated system of the supervisory control moisture in the irrigation system. Goal - improving the efficiency of the automated control system of the irrigation system by optimizing the operational control of moisture through the use of adaptive control methods with predictive model. Methods - regression analysis and mathematical statistics, numerical methods, apparatus of the theory of fuzzy sets, the methods of modern control theory, methods of spectral analysis. For the first time the mathematical model of the dynamics of moisture in the state space, which allows the analysis of soil moisture at the desired point of the plow layer is obtained; the continuous mathematical model of dynamics of moisture in the form of approximating shells, which allows to describe the functioning of distributed objects is proposed; the goal functional to determine the optimum moisture management in a geographically distributed system is formulated. Were further developed: methods of determining the optimal placement of sensors circuits, methods of formation of optimal control that reduce the identification error. Improved: decision support system for automated dispatch control module estimation of soil moisture and the adaptive control module with the predict; monitoring subsystem through the use of wireless technologies in the data transmission system and optimize the placement of sensors. Scope - in the agricultural industry to improve decision support systems in CAD/CAM irrigation services for the planning of water distribution.
