Research of frequency converter with vector-algoritmic control

The article discusses the possibility of using a frequency converter for mechanisms that require several speeds of rotation, both fixed and with the possibility of smooth change. A developed frequency converter with vector-algorithmic control is proposed and the result of mathematical modeling of the proposed frequency converter in comparison with a direct-acting motor in the MATLAB Simulink environment is presented. This frequency inverter adopts a simple control system that can be executed in various ways to adjust the rotational speed of a three-phase induction motor. In addition, a physical model of a frequency converter with vector-algorithmic control was developed and assembled, and a comparison of the physical and mathematical models was made.
