Abstract :
In sensorless vector control of induction motor using voltage-fed inverter, the flux estimation error caused by stator voltage error due to the dead time and switch voltage drop and so on can deteriorate the performance of vector control. This paper proposes a method to compensate the stator voltage error by utilizing the error value between the measured current and estimated current. The DC component and fundamental component of reconstructed stator voltage errors have been compensated
