The paper provides a methodology of the difficult hydropower-driven systems equipped with primary energy sources of two types: explosive motors and the electric motors operating under trying conditions of maintenance. The latter, alongside with hydropower-driven systems, are modeled as uniform heat-electro hydromechanical systems, optimum control with which one can carry out on the basis of a mechanotronic approach and a principle of a maximum developed by L.S. Pontrjagin. The method for investigating dynamic operating modes of electrohydraulic drive systems with movable boundaries of operating fluids was described. The method is original as it allows one to calculate dynamic operating modes of the abovementioned systems in the cases when fluids of these systems have movable boundaries of the following type: “fluid–gas” or “fluid–solid” (“fluid–piston”). The description of engineering, physical, and mathematical models of the investigated processes was presented.
