Vehicle drive motor current-sensorless control method

• 摘要：

  A current-sensorless control method was proposed to apply in the vehicle drive motor to alleviate the shortecomings of the traditional vector control (narrow efficient work area) and the feedback loop control (being liable to over current). This method directly controls the magnitude and phase angle of the voltage vector according to the command motor torque and speed to realize the control of the real torque and speed of the motor. The proposed method saves the cost of the current sensor, avoids the dependence on the current sensor, the possible over current of the close loop control, and being unable to control under the condition of the current sensor malfunction. The simulation and bench test results show that the proposed method can not only increase the efficient work area, but also improve the reliability of the motor control system.
