摘要：

allusion to the characteristic of direct torque control system, the state equation for extended Kalman filter was established by stator variables. The real-time forecasting and filtering iterative algorithm were founded in order to real-time control. Speed and stator flux can be discerned through the stator current and voltage, and the speed-sensorless direct torque control for asynchronous motor was realized. Simulation results show that the speed have a high accuracy and a good robustness.
