| Abstract: | The control strategy for the direct torque control of the permanent magnet synchronous motor＇s sensor based on space vector modulation is proposed, and the model reference adaptive system method for identifying motor speed is applied to the control. Matlab / Simulink is used to simulate the control system, and drawing on SVM-DTC method, an experiment is conducted on the permanent magnet synchronous motor The simulation and experiment show that the strategy has good properties of stability and dynamicity capable of having fast dynamic response, effective reduction of the torque and current ripple, and improvement of the control performance of the system. |
