Документ Informational support of the automated control system for baking production(2018) Pankov, Dmitry; Kyshenko, VasilIn order to increase the efficiency of production in the baking industry, a special role is assigned to the automation of technological processes implemented on the basis of intelligent mechanisms and modern microprocessor technology. The main reserves for improving efficiency through automation are improving the quality of baking products, the use of resource-saving technological regimes and increasing productivity of production. Taking into consideration the high lability of the raw materials characteristics, the current problem of automation in baking plants is operational complex evaluation of the quality of raw materials in real time, semi-finished products and finished products by methods of dynamic quality control. The solution of such problems is possible only on the basis of modern intellectual technologies and advanced achievements in the theory and practice of automated management. To ensure optimal management of the technological complex of bakery production, it is necessary to use a system of support and decision making based on an expert system.Документ The analysis of sugar plant as a complex nonlinear and dynamic object of control(2016) Kyshenko, Vasil; Sych, MarynaFor the efficient control of the technological complex of a sugar plant, as a complex nonlinear control of object is necessary to analyze time series of algorithms using of nonlinear dynamics, namely to determine the Hurst exponent, correlation dimension and recovery phase space.

A great importance of an evaporator plant is admitted not only in a technological complex, but also in a heating complex of a sugar factory as a supplier of secondary steam for other subsystems of technological complex, such as vacuum devices and various heaters, to ensure their proper functioning.Документ Development of the Algorithm of Determining the State of Evaporation Station Using Neural Networks(2016) Ladanyuk, Anatoly; Kyshenko, Vasil; Shkolna, Olena; Sych, MarynaFor the rational use of thermal resources with the help of optimal control of evaporation station at a sugar factory, it is necessary to carry out the operation control of the states of evaporation station, which is determined based on the current assessments of technological parameters such as levels and temperature in cases of a station, juice and syrup consumption, thermophysical characteristics of vapor as well as the level of its consumption by technological plants of the factory. The algorithm of determining the state of evaporation station as a control object based on intelligent methods of clustering and classification was developed. The applied method of clustering based on the Kohonen self-organizing maps allowed defining a set of possible states of the object on the basis on information hidden in time series of technological parameters of evaporation stations. The application of the method of fuzzy classification allowed determining the state of evaporation station in the current moment based on the values of current parameters of evaporation station and the obtained set of possible states of an object. The developed algorithm of determining the state of evaporation station as a control object is expedient to use in automated control systems with the purpose of operational determining the state of control object in order to make timely decisions on optimal control of evaporation station.Документ Scripted control of technological process of the sugar prodaction(Kyshenko, V.

The applied method is built on such a property of a complex system as recurrence. This method of analysis is based on the representation of the properties of a complex object of management in the form of geometric space-time structures and their quantitative assessments. It, accordingly, makes it possible to carry out a prompt analysis of its behavior for making resource saving management decisions. When creating information management systems of complex objects there is always a task of assessing their state. This is caused by a continuous change in both the external environment and the object’s parameters, which is relevant for a technological complex of a sugar plant. It was established that the character of the processes that occur in the technological complex of a sugar plant is predetermined by the intermittency in behavior while it is also subject to laws of the theory of dynamic chaos. Chaotic behavior of technological objects was explored by the methods of nonlinear dynamics, which allowed us to determine qualitative and quantitative assessment of deterministic chaos. This, in its turn, makes it possible to develop of efficient systems of synergetic management that ensure maximal use of own resources of the object of management owing to the phenomena of self-organization.
