摘要： The invention provides a sensorless control method and apparatus of a permanent magnet synchronous motor where magnetic axis can be assigned in all speed regions and speed can be controlled continuously irrespective of the speed command. In the control method, the d-q axis being the magnetic axis rotating in the real rotation speed omega R of the motor is set and also the gamma - delta axis being the assigned magnetic axis of the motor is set, and when the rotation speed omega R gamma of the gamma - delta axis is determined, a distribution gain K1 is set so as to be decreased as the absolute value of the rotation speed command omega RREF becomes large and a distribution gain K2 is set so as to be increased as the absolute value of the rotation speed command omega RREF becomes large, and the rotation speed command omega RREF is multiplied by K1 and the speed estimated value omega RP determined from the induced voltage of the synchronous motor or the induced voltage estimated value is multiplied by K2 respectively, and both multiplied values are summed thereby the rotation speed omega R gamma of the gamma - delta axis being the assigned magnetic axis is determined.
