Abstract
Frequency-controlled electric drives are used in various industrial sectors due to the simplicity and reliability of the electric machine design, as well as the ability to provide the required control characteristics. This paper presents a mathematical model of a frequency-controlled electric drive with voltage source inverter developed by the Average Voltage in the Integration Step (AVIS) method and confirms its adequacy. A comparative analysis for the speed responce and accuracy of the model calculation by the AVIS method, compared to known methods in Matlab/Simulink and to the known results of physical experiments, demonstrated the efficiency of using the AVIS method for modeling frequency-controlled induction electric drives in phase coordinates with taking into account the actual curves of currents, flux, and torque of electronically commutated induction machines.
