Abstract :
A new control method of induction motor is proposed in this paper to reduce the pulsation of motor torque and magnetic flux linkage, which, as a great disadvantage, exists in the direct torque control system. According to the conclusion, the required voltage vector is provided which can be composed by space voltage vector pulse width modulation. Simulation results show that it effectively solves the problem of torque ripple and flux ripple
