Abstract in English: 

Background: The use of electromechatronic modules in many cases changes mechanical parameters or makes their determination difficult. The main direction in solving this problem is the use of additional circuits of identification and adaptation. An alternative variant is using regulators of a complicated algorithmic structure based on neural networks, fuzzy logic and genetic algorithms. Such solutions are not always suitable when a fast response and a competitive price are required. Positioning systems of electromechatronic modules adjusted to Bessel’s dynamics have structurally simple position regulators. Therefore, it is quite urgent to theoretically and practically justify fixed settings of regulators at a certain level of reduced mechanical inertia, which is the object of this study.

Materials and methods: Parameters of static and astatic positioning systems have been analyzed by the methods of modern automatic control theory in accordance with the requirements of the area of practical implementation of electromechatronic systems. The positioning system parameters were obtained by symbol mathematics tools MathCAD and simulation in the Simulink (Matlab) environment by using Linear Analysis instruments.

Results: By employing methods of classical analysis of control systems and computer mathematics potential, the authors have proved that it is possible and efficient to use fixed setting of static and astatic regulators of positioning systems of rigid mechanics electromechatronic modules if mechanical inertia parameters vary within a wide range of values.

Conclusions: The authors have theoretically justified the recommendations to fix the static and astatic position regulators at the maximum level of reduced mechanical inertia. The positioning systems of electromechatronic modules with such settings have stable parameters.

Key words: control systems, electric drive, position regulators, characteristic polynomial, fixed setting, positioning system.
