Abstract: Introduced the theory and frame of direct torque control in this paper.Completed A whole control system design included hardware and software based on DSP has coupleted.Experiments have been done based on a YF906 type three-phase asynchronous motor.The results prove that this hardware circuit has a reasonable construction with good control function and protect measure.This system can be used for some more complex control strategy.
