AVIS method

This paper presents a high-speed mathe-matical model of an induction motor in phase coor-dinates designed for real-time operation on the efficient ESP32 microcontroller platform. The model is based on the method of average voltages in an integration step which ensures high computational speed and numerical stability. The software implementation in the ESP32 microcontroller utilizes the Eigen library and the Free-RTOS operating system to enable real-time performance.

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.
