SVM-FL-DTC Control Induction Motor Drives Fed by Indirect Matrix Converter

Abstract

This paper proposes a fuzzy logic direct torque control strategy to control the speed of the induction motor (IM) which is fed by an indirect matrix converter (IMC). For the matrix converter rectifier stage, a space vector modulation (SVM) technique is adopted; moreover, for the matrix converter inverter stage, the technique fuzzy logic direct torque control (FL-DTC) is used. The torque reference is synthesized from the difference in speed (motor speed and reference speed) using a PI controller. The performance of the proposed drive system is evaluated by numerical simulation using the Matlab/Simulink environment. The simulation results are used to verify the effectiveness of the proposed strategy compared to the analytical results obtained.
