Abstract
We have developed control system for a fermentation unit process based on a fuzzy controller. The objects under control are fermentation tanks located at “Bashspirt” Joint-Stock Company. The process of saccharifiedwort fermentation is carried out by yeast. The task was to improve the process of fermentation of saccharifiedwort by yeast and replace the outdated control system with a newer and more modern one. In this regard, a fuzzy controller system has been designed to control the process of fermentation unit capable of controlling the following twelve output parameters: valve position for supplying wort to six fermentation tanks and for supplying yeast to six fermentation tanks. Twelve control output parameters control the following seven input parameters: the fill level of the prefermenter, the fill level of six fermentation tanks. The output parameters are controlled on the base of the information obtained from the wort and yeast input level sensors. The introduction of an automatic control system that takes into account the basic parameters of a multi-connected object and is capable of controlling the entire process of the fermentation unit allowed to solve the following problem: stabilization of the input parameters and the output process parameters control.
