In order to realize the torque control accuracy of the electric drive system under the influence of the deviation of permanent magnet supply,the temperature deviation of permanent magnet,the current sensor accuracy deviation,the voltage sensor accuracy deviation,the calibration temperature management deviation and the initial angle detection influence deviation,simulation and test were conducted to obtain the influence factors under the independent action of the above factors,and statistical principle was used to obtain the torque control accuracy range of the comprehensive influence factors,which was tested and verified on the prototype.Test results show that the accuracy of the torque value calculated by this method is within the range of-1.1%~2.8%,which meets the product requirements.
