“…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].…”

“…In previous papers by the authors [5][6][7][8], it was shown that in complex, multi-parameter mechanical systems, it is recommended to use dimensionless models in which the actual parameters and other characteristics of the system are represented as dimensionless complexes. This reduces the number of basic parameters and allows us to obtain generalized characteristics, which facilitates the analysis and synthesis of the drive (mechatronic) complex.…”

“…However, there is little information about the methods of synthesis and optimization of the structure and parameters of such systems. To solve such problems, it is proposed to use the approaches developed by the authors based on an interactive procedure for the synthesis of dynamic systems, rationalization of their mathematical models, methods of matching the processes of dynamics and control of individual blocks, as well as the active use of similarity theory and, in particular, the analogy theory, in order to summarize the results [5][6][7][8]. In present work, this problem is solved by the example of controlling the movement of a heavy object moved by two synchronously working piston hydraulic engines.…”

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.

Mathematical models describing technically oriented dynamical systems are generally rather complex. Very time-consuming interactive procedures have to be used when selecting the structure and parameters of the system. Direct enumeration of options using such procedures can be avoided by applying a number of means, in particular, dimension methods and similarity theory. The use of dimension and similarity theory along with the general qualitative analysis of the system can serve as an effective theoretical research method. At the same time, these theories are simple. Using dimension and similarity theory, it is possible to draw conclusions when considering phenomena that depend on a large number of parameters, but so that some of them become insignificant in certain cases. The combined method of using the theory of similarity, analogousness and methods developed by the authors for testing the drive model provides insight into its dynamics, controllability and other properties. The proposed approach is based on systematization and optimization
