Abstract The goal and problems of this paper consist in development of fuzzy model that is applied to control of production objects in the uncertainty conditions with following estimation of model’s accuracy. The existing solving of this task by usage of classical control theory in the uncertainty conditions doesn’t allow to provide effective controlling of the named objects and leads to reducing of results’ accuracy. The classical control theory can’t take into account uncertainty and also we can’t develop the accurate mathematical model. The solving of the given problems is described in this paper in the following way. The usage of fuzzy set theory and fuzzy logic for control of production processes in the uncertainty conditions is proved. The structure of fuzzy model is developed. The offering structure distinguishes from others by usage of its estimation. The sequence of actions by development of fuzzy model for controlling of the production objects is determined. The function of model’s blocks is considered. The fuzzy control model of production objects is developed by the example of temperature control’s process at the baking chamber. The problem of effective control of temperature at the baking chamber is actual now. The inputs and outputs are set, that are set on the verbal level. Also the determining of make decision’s rules by experts is considered and an example of membership functions’ assignment is given. The features of control solution’s inference are described. The analysis of experimental researches is carried out, the given data confirm a hypothesis of expedient applying of fuzzy methods for control tasks of production objects in the uncertainty conditions. Finally, the result of this paper consists in development of systems approach in the solving of control tasks of thermal processes, that are characterize oilrefining, chemical, metallurgical, power, food industries in the uncertainty conditions.
