“…There are several methods for finding and choosing the optimal solution in the synthesis of a complex system, including methods of multicriteria optimization with the introduction of weight criteria [5,7] or taking into account preferences. This work is devoted to the stage of data preparation for the use of these methods, for which the results of computer simulation, presented in a visual for viewing, are interactively compared [10,11].…”

The paper presents a dimensionless mathematical model of the dynamics of the drive complex and the visualization of the solution of this model, which allows to obtain comparative estimates (characteristics) of the solutions obtained in the first approximation.The authors proposed an original control system for the drive complex of two hydraulic actuators to lift the load in parallel mode. A distinctive feature is the adopted control circuit of the complex through three hydraulic switchgears, which are responsible for regulating the overall object lifting (and/or lowering) speed and maintaining the horizontal position of the object within the specified accuracy in the presence of disturbing factors of different nature. The difference in displacements of the hydraulic actuator rods from some initial (basic) position at a given time is a sign of deviation of the object from the horizontal position. The mathematical model of the object obtained is investigated in dimensionless variables, which greatly simplifies the visual synthesis of the object.
