【Abstract】 In order to enhance the performance of induction motor, based on the direct torque control, combining the characteristics of both state - flux - oriented control and rotor - flux - oriented control, the scheme of speed estimation for motor in detail is discussed. A simple and applicable speed estimation method of AC motor is put forward. The speed sensorless direct torque control based on DSP (TMS320F2812) for asynchronous motor is implemented. The result shows the theory analysis is right and the scheme is reliable.更多还原
