초록

This paper present a new speed sensorless control algorithm of a permanent magnet synchronous motor based on instantaneous reactive power. The proposed algorithm is constructed by instantaneous reactive power in the stationary reference frame and is not affected by mechanical motor parameters, because mechanical equation is not used. The effectiveness of the proposed algorithm is verified by the experimental results.
