| Abstract: | The effect of stator resistance variation on direct torque control(DTC) of permanent magnet synchronous motor(PMSM) is analyzed.By means of comparing the actual current and the reference current,the change of stator resistance can be tracked and the stator resistance can be on-line estimated.Simulation results demonstrate the method could accurately estimate the stator resistance and improve the DTC performance. |
