Speed and Position Sensorless Vector Controlled Drive of the Permanent Magnet Synchronous Motors

속도 및 위치검출기를 사용하지 않은 영구자석 동기전동기의 벡터제어

The traditional speed and pole position sensors, which are inevitable to drive the permanent magnet synchronous motors, are removed by the parameter identification using model reference adaptive systems. Also, the current detecting method is proposed on the synchronously rotating axis without the position information, and this enables the implementation of the proposed algorithm. The proposed methods have been confirmed both by digital simulation and experiments.
