| Abstract: | Introduces the basic structure and the working principle of the direct torque control system of asynchronous motor.Based on the control system of circular flux linkage track and combined with the characteristics of the mine hoist speed regulating system,a simulation model which can directly control the speed regulating system of the torque is made by MATLAB6.5/Simulink5.0 with use of the flux linkage observation model and the torque observation model in the asynchronous motor α-β coordinate system,proposed the measure of reducing the system torque pulsation.The simulation result suggests that the model is correct and the improvement plan is effective. |
