| Abstract: | A novel direct torque control method based on vectors subdivision and SVPWM is presented in this paper. This novel control method is applied to the speed regulation system of asynchronous motor. The simulation testing indicates this control method can get low torque pulsation, less current harmonic, constant switch frequency. The speed regulation system has both good dynamic performance and high accuracy of the speed regulation. |
