| Abstract: | On the basis of the stator flux oriented control theory,a method of the direct torque control is presented in this paper.The decoupled control for pulse width modulation inverter fed induction motor is realized by dynamic calculation of the induction motor stator voltage vector.The proposed method has better performance in torque and magnetic field than vector control.The test's result demonstrates the proposed method is correct and effective. |
