СИНТЕЗ НЕЧІТКОГО РЕГУЛЯТОРА ТЕМПЕРАТУРИ ПАСТЕРИЗАЦІЇ МОЛОКА

Abstract

The article solves the actual scientific and technical task of reducing the energy intensity of pasteurization of milk in the POU5 apparatus by means of research and development of an automated system for controlling the pasteurization temperature regime. A study of the features of the device's functioning, setting the parameters of the control process was carried out; the improvement of the mathematical model and the algorithm for regulating milk pasteurization parameters was carried out; an automated system for controlling the temperature of milk pasteurization in the POU5 installation was created. The synthesis of a fuzzy regulator of milk pasteurization temperature was carried out. Constructed response surface of milk temperature changes depending on the consumption of milk for pasteurization and the temperature of the hot water of the heat exchange r. The application of the fuzzy logic apparatus for building an adaptive system makes it possible to create adaptive systems with optimal control for the purpose of approximating the output variable of the fuzzy controller.A structural scheme of the milk pasteurizer was created, as well as effective methods of temperature control and para-metric schemes of sections (recovery, pasteurization and cooling of the plate milk pasteurizer) were developed, which allow improving the accuracy of technological process control.As a result of conducting theoretical research, a dynamic characteristic of the pasteurization section was obtained ac-cording to the channel «hot water consumption - temperature of pasteurized milk». The specified model will allow to develop temperature control algorithms to increase pasteurizer productivity
