Patent ID: 7006906

Claim:
An electric drive control apparatus, comprising: an electrically operated machine; instruction value calculation processing means for calculating an instruction value based on a target electrically operated machine torque representing a target value of the electrically operated machine torque and on a rotational speed of the electrically operated machine; output signal calculation processing means for calculating an output signal based on the instruction value; a current generating unit that generates a current based on the output signal and that supplies the current to the electrically operated machine; change-in-the-voltage-saturation calculation processing means for calculating, based on the instruction value, a change in the voltage saturation that varies depending upon the degree of occurrence of the voltage saturation accompanying the drive of the electrically operated machine; and change-in-the-control-quantity correction processing means for correcting a change in the control quantity based on the change in the voltage saturation, the change in the control quantity being a magnetic pole position of the electrically operated machine.
