摘要：

The authors have proposed a method to estimate the pole position for sensor-less IPMSM drives with only DC link current measurement and use a triangular comparison PWM technique. Using the proposed method, the current control has not to be interrupted and the band-pass filter is not necessary. The proposed method needs the current detection at apexes of triangular carrier waves, precisely. So the effect of the detection timing delay and the effect of the dead time are investigated. A method to compensate the pole position estimation error is also proposed.
