The dynamic performance of speed control of an induction motor has been known to be very sensitive to unavoidable disturbances such as unbalanced input supply and variable load torque. The effect on the controller performance further impacts the dynamic speed response and Total Harmonics Distortion (THD) of the system. Having a speed controller with good dynamic performance response, reliable handling of disturbances, high system efficiency, and low THD values is crucial in induction motor drives but challenging to accomplish. A matrix converter could potentially address the issues due to its reliability and efficient properties. In this paper, the Fuzzy Supervisory Controller (FSC) is embedded in a scalar control matrix converter fed induction motor drive with Indirect Space Vector Modulation (ISVM) to produce a reliable control system with improved dynamic performance. Reliability is evaluated by introducing voltage imbalance on the input and output sides of the motor drive. Based on the results of this work, the proposed controller can produce reliable speed control with good dynamic performance, work well under disturbances, and minimize current and voltage THD levels. © 2021, School of Electrical Engineering and Informatics.
