Abstract: To facilitate the design of the direct torque controller for doubly fed induction motor（DFIM）,a space vector’s mathematics model and equivalent circuit of the DFIM in the rotor coordinate were established,the expressions of the electromagnetic torque and rotor flux linkage were deduced.By analyzing the influence of rotor voltage space vector on rotor flux and electromagnetic torque,a novel direct torque control for DFIM was presented,which included two parts:the relative location of the rotor fl... More
