A Novel MATLAB/Simulink Model of PMSM Drive using Direct Torque Control with SVM

A modified Direct Torque Control (DTC) by using Space Vector Modulation (DTC-SVM) for permanent magnet synchronous machine (PMSM) drive is proposed in this paper. DTC-SVM technique improves the basic DTC performances, which features low torque and flux ripple and also fixed switching frequency. The computer simulation results, in Matlab/Simulink, demonstrate the effectiveness of the proposed control scheme which improves the performance of the PMSM.
