Abstract :
A new fuzzy direct torque control scheme for permanent magnet synchronous motor drive is proposed in order to improve system stability and reduce the ripple of torque and stator flux linkage. Zero voltage space vector is used to obtain a new fuzzy-ruler table. So, Fuzzy rulers are simplified for shorting computation time. Finally, simulation results verify the superior operation performance.
