Abstract
In article the problem of synthesis of the regulator which is reduced to determination of adjusting parameters of self-alignment of object of management (a ship auxiliary copper) and training of regulators of object on statisticians of management is analyzed. Heat supply facilities which treat and ship auxiliary coppers have effect of self-alignment, at the expense of a lag effect of processes of change of the modes of loading, processes of supply of fuel and a consumption of air, and also the modes of giving of feedwater. Owing to these reasons development of digital processors of management demands the accounting of the factors realizing effect of self-alignment of a copper. Considering technological complexity of object, to realize settlement model completely corresponding it isn't possible to real object. The only almost acceptable way is a realization of indistinct management on technical characteristics of a prototype – the existing copper. The second important factor, approach the considering type of regulators of object serves, to the relevant system of relay type. Such assumption allows to realize linear approximation of characteristics. The accepted assumptions allowed to formalize process of synthesis of the regulator of relay type in the Fuzzy Logic editor of MatLab system. The realized model, control systems provides possibility of practical use of technology of indistinct modeling in the environment of MatLab for the purpose of obtaining adjusting parameters of regulators with further realization in low-digit digital microcontrollers.
