Abstract
Filter in voltage detection can cause phase lag, which affects the estimator in the range of high speed.Voltage detection was replaced by voltage reconstruction algorithm to solve the problem while researching the parameter identification and sensorless control algorithm of TI 28069 M.The effect of real dead time on the voltage reconstruction was analyzed.Using the characteristic that the stator resistance identification results of the same motor remained the same, the method to get the real dead time by identifying the resistance twice was designed, the voltage reconstruction formula was completed and the accuracy was enhanced.The parameter identification and sensorless control experiments were carried out by using the voltage reconstruction instead of voltage detection.The results show the effectiveness of 28069M algorithm and the practicability of voltage reconstruction can be used in practical application.关键词
