frequency converter

In modern industry, the most widely used are adjustable electric drives of the ‘Frequency converter - induction motor’ (FC-AM) system, in which integer-order controllers are mainly implemented and used. The use of fractional-order controllers in electromechanical FC-AM systems allows to ensure: higher quality of transition processes, increase the stability margin and reliability of the system, higher robustness to changes in motor parameters and, as a result, guarantees higher performance compared to classical integer controllers.

Positional electric drives are widely used in various branches of mechanical engineering, metal- cutting and woodworking machines, excavators, hoisting and transport mechanisms, manipulators.

A comparative analysis of the characteristics of a position tracking system, which is represented by asynchronous and synchronous mechanically unconnected electric drives, has been described in the article. The one electric drive operates in the Master mode and the other works in the Slave mode in such systems.
