To the subject of structural control of dynamic flow distribution

The work is suggested that represents a further extension of the methods related to the theory of hydraulic circuits of V. Ya. Hasilev and A. P. Merenkov in the direction of the substantiation, mathematical description, and statement of problems of regulation and control, which involve the nonstationary flow distribution in multiloop hydraulic circuits with lumped parameters. Consideration is given to a structural change in the diagram of a hydraulic circuit by way of a sequential exclusion of branches (edges) of the graph, which does not lead to its decomposition. The statement and description of this kind provide a model representation of the problem of structural control of actual piping systems, in particular, engineering systems of water and heat supply.
