| Abstract: | Focused on the defaults of "Dead Beat" control methodin the Direct Torque Control theory, this article presents a new control strategy-the flux real time control method, and then sets up the selection principles of the inverter switching state. Moreover, to the stator current signal and its spectra, a key sector that influences the system performance, this article gives a detailed discussion and gets a conclusion. |
