Abstract: This paper researched the indirect torque control Strategy for doubly-fed induction motor.first of all,gives the mathematic model of doubly-fed induction motor,flux and torque observer adopts current model avoids integral errors.and then gives a detailed deduction of indirect torque control algorithm of doubly-fed induction motor. last,MATLAB/Simulink simulation software was used for the this system. And the feasibility and effectiveness of the algorithm was confirmed by the simulation results .The simulation results show simple structure, lower calculation, fast response ,precision of control.
