- Abstract
The basic direct torque control (DTC) scheme may cause big ripples in torque, flux and current because of the small number of applicable voltage vectors. And the variation of the stator resistance has great influence on torque and stator flux estimation especially when the PMSM(permanent magnet synchronous motor) run in a low speed. Several methods are proposed to solve the problems above in this paper. First a SVMDTC (DTC using SVPWM) method is used which decreases the torque and flux ripple considerably. Second a fuzzy stator resistance compensator is introduced to overcome the mismatch between the stator resistance in control algorithm and the actual stator resistance.
