Abstract :
An improved direct torque control (DTC) scheme based on the effect of voltage vector on torque for permanent magnet synchronous motor (PMSM) is proposed in this paper, which can increase useful voltage vectors in a sector to 6. Simulation results show that can lower unreasonable torque ripple effectively.
