Abstract:
A synchronous machine control device is provided with a magnet state outputter that estimates a magnetic flux of a permanent magnet forming the magnetic field of a synchronous machine. In a magnet state correction value calculation mode, the magnet state outputter calculates a magnet state correction value. In a magnet state estimation mode, the magnet state outputter obtains, from a magnet state estimation device, a magnetic flux estimation value of the permanent magnet under a given condition of a magnetic flux command and a δ-axis current command and controls a magnet state corrector to correct the magnetic flux estimation value of the permanent magnet obtained by the magnet state estimation device, by use of the magnet state correction value.
