摘要

A sensorless vector control apparatus is provided to improve the performance of the sensorless vector control by performing double integration of a firs term and estimating the magnetic flux of a rotator and the current of stator. In a sensorless vector control apparatus, a state observation unit applies instruction the voltage of a stator, speed estimate and the resistance estimate of the stator to a differential state equation and obtains the estimate current of the stator and the estimate magnetic flux of the rotator by integrating the output of the differential state equation. A seed/ stator resistance estimating unit(2) receives an error current of the stator and the magnetic flux of the rotator and estimates speed estimate and stator resistance estimate.
