Audit of control algorithm quality of drum steam boilers at design stage of automation system

Abstract

Investigation of complex engineering objects and improving the quality of their management in the classic version come to carry out the decomposition of the object into multiple control loops, which in turn imposes certain limitations in the practical application of research results, and leads to loss of information on the impact of parameters on each other. Therefore, the implementation in practice does not provide a research control facility as a whole. Experimental and analytical complex model of dynamics of drum boiler for all areas of regulation is developed. Algorithm and logical-structural scheme of models allow studying a synthesis of control algorithm of the entire object, to analyze the results on the basis of the transients. The physical implementation of the model assigned to the industrial freely programmable logic controller of module form factor. It is used as a base for the practical implementation of control algorithms. The result is a closed self-contained control system and simulation modeling, which has the ability to interface with external controls on the physical or logical level.
