Abstract

Introduction: Development and practical application of energy-saving control systems for complex technological objects is a pressing problem because it allows you not only to improve the product quality but also to significantly reduce the energy costs. One of the most difficult stages in the development of an energy-saving control system is developing its algorithmic support, as the models and algorithms should take into account all the specific features of the controlled object and provide the required characteristics of accuracy and performance. Purpose: We analyze the energy-saving control problem in order to determine the conditions under which it can have a solution, and to specify the possible types and parameters of the optimal control functions. Results: A complete analysis of the energy-saving control problem is presented for the dynamic modes of a tumble dryer. The energy-saving control problem is formalized for the dynamic modes of the technological process of drying DDGS. An algorithm is shown which finds out whether the optimal control problem can have a solution. The types are defined for the functions of optimum control, along with the ratios for calculating their parameters for the functionals “minimum fuel consumption” and “minimum energy expenditure”. The comparison of the obtained functions has shown that they provide the same value of the functional, but in some cases “minimum energy expenditure” should be preferred. Practical relevance: The obtained results allow you to develop operational algorithms of synthesizing control actions for energy-saving dynamic mode control system of a tumble dryer.
