| abstract | PURPOSE:To effectively correct an amplitude in response to a saturating characteristic of a motor at high rotating speed with less torque ripple by correcting the amplitude and correcting a phase delay due to an iron loss. CONSTITUTION:A current value I1 necessary to generate a magnetic flux density phiproportional to a current command value I0 is calculated by magnetic flux density calculating means 12 by the data of saturating characteristic memory means 11 for storing the saturating characteristic of a magnetic circuit of a motor 40. Static gain correcting means 13 compares a current command value I0 with a current value I1 and amplifies it as required. Phase/gain characteristic memory means 21 stores a phase delay and amplitude loss due to the iron loss of the magnetic circuit of the motor 40. Dynamic characteristic correcting means 23 compensates the phase of a signal output from the means 13 on the basis of a value output from phase/gain characteristic memory means 21. |
