Structures and efficiency areas of object control systems with various types of recycling

The work is devoted to the study of automatic control systems (ACS) of objects with various types of recycling. The characteristic feature of such objects is the presence of a delay element in the coordinates. It is known that only with the help of recycling the use of raw materials and energy resources can be maximized. However, little attention has been paid to the control of such objects in the well-known publications, which gives the study a particular importance. The paper describes a classification of objects with recycling proposed by the authors with the identification of four classes of objects: recycling “by concentration”, “by mass”, “by parameters”, combined recycling. ACS are synthesized for the first three classes of objects. The task of comparative analysis of the systems effectiveness with a model control law and the proposed synthesized systems is set, as well as the task of determination of areas of systems effective operation depending on the variable value of the ratio of the delay time in the recycling chain and in the direct circuit, the conclusions are drawn.
