MATLAB-Arduino as a low cost microcontroller for 3 phase inverter

This paper presents the performance of the Arduino microcontroller board in response to an advanced control strategy for a motor control application. Two set of control theories have been used and combined as known as the Proportional Integration (PI) - Repetitive controller. This controller has been designed in MATLAB-Simulink environment and then downloaded to the Arduino for testing. The test set consists of 3 phase inverter, filter, induction machine (IM) and a set of current controller. The feedback current from the IM will be the control parameter for the controller and the Arduino in order to generate the pulse width modulation (PWM) pattern. Different PWM pattern is generated when the feedback current is changing due to the changing of the load.
