Abstract

The article works out the structure of the relationship between the managerial levels of the food enterprise, which is developed taking in-to account the use of robust control systems in the abnormal mode and systems of repair of heat power. To optimize renewable energy systems to the existing range of technological equipment of the bakery, a cogeneration unit is installed, due to its ability to generate and consume both heat and electricity. Also it is shown that the emergence of an abnormal situation at the electrotechnological complex of food production leads to a significant change in the transfer coefficients of the object over the direct and cross-channel channels, which will lead to loss of stability of the closed control system. Synthesized structure robust control system which has roughness properties and minimal sensitivity to parametric and structural uncertainties facility in case of emergency situations and elected its optimization criterion. The basic properties of the electrotechnological complexes of food industries are analyzed and on the example of the baking furnace the robust control system synthesis and renewable energy systems are shown. A comparison of the characteristics of the control system with local and robust controllers has shown that a robust controller system has better robust properties in case of emergency situations.

Highlights

Systems of automated control of the food industry electrotechnological objects at the regular mode operate according to the criterion defined by the technological regulations [1], this may be an integral quadratic criterion, minimization of the time of regulation, etc
In order to simplify the implementation of robust control systems by the electrotechnological complex of food production in a non-regular mode, a generalized universal structure of the interconnection of managerial levels of the food enterprise with the consideration of renewable energy systems has been developed
A simulation of the system of automatic temperature control in the boiler house was carried out to assess the boiler operation mode taking into account the amount of renewable thermal energy produced by the cogeneration unit

Summary

Introduction

Systems of automated control of the food industry electrotechnological objects at the regular mode operate according to the criterion defined by the technological regulations [1], this may be an integral quadratic criterion, minimization of the time of regulation, etc. In this case, the calculation of control device configuration parameters is usually carried out for a linear model with constant coefficients taking into account the stability of the system. In order to ensure the stability of the system, it is proposed to use robust control systems in the abnormal mode
