Design and Implementation of Microcontroller Based Three Phase Induction Motor Experimental Set

Electrical engineering students face multiple challenges during studying electrical machines drives and control. One of the most common difficulties is to find an experimental kit that has the flexibility to implement any desired approach related to control algorithms, and switching functions. This paper proposes an educational, open-source, and fast experimental setup to provide the students with the ability to perform open and closed-loop speed control of three-phase AC machines. The proposed setup consists of a STM32H735G microcontroller, three-phase inverter, measurement board, speed sensor, and induction motor (IM). Although various speed control applications can be conducted by this set, this paper focuses on the
$v/f$
method as a case study. The experimental setup provides the ability to perform open and closed-loop control, real-time monitoring, graphical user interface (GUI), variable frequency, variable modulation index, variable proportional gain, and variable integral gain. Moreover, this solution can be used in a wide range of experimental setups including AC drives, DC drives, inverters, and rectifiers.
