Effect of Number of Data Tuples on Results of Mixed Control of the Neighborhood Model

A bilinear neighborhood model of the plant for maintaining the polyol optimum temperature is considered. The structural model of the plant and its essential parameters are presented. Neighborhood models are identified for one, three, five and seven data tuples. In order to determine the heat transfer coefficient, traditional mixed control and mixed control with the restrictions imposed on the possible variation of the variable coefficients by damping were implemented. The results of determining the heat transfer coefficient by means of two variants of mixed control are compared with the results of thermotechnical calculation.
