Abstract :
To minimize the ripples of the electro-magnetic torque and flux linkage and to fix the variable switching frequency produced in the conventional direct torque control (DTC) system for permanent magnet synchronous motors, this paper proposes a space vector modulation (SVM) DTC concept. Both simulation and experimental results show that the proposed SVM DTC can dramatically improve the steady state performance while preserving the dynamic performance of the conventional DTC.
