| Abstract: | In this paper, direct torque control based on the predicted voltage space vector of permanent magnet synchronous motor is analyzed and derived according to the mathematical model of the permanent magnet synchronous motor. Direct torque control using traditional hysteresis control and direct torque control based on the predicted voltage vector have been studied contrastively through simulation. The results show that the current fluctuation and torque ripple has been greatly improved using the deduced method. Finally, it is verified that the proposed method can reduce the current fluctuation on the experimental platform. |
