<P>PROBLEM TO BE SOLVED: To improve follow-up capability of an electric machine, for less fluctuation in torque. <P>SOLUTION: The arrangement comprises an electric machine, a rotational speed detecting part for detecting rotational speed of the electric machine, a deviation calculating means which calculates deviation between the target value of the rotational speed and the rotational speed detected by the rotational speed detecting part, an adjusting value calculating means which calculates the prescribed adjusting value corresponding to the deviation, and a target value calculating means which calculates the target value of the torque of electric machine at a prescribed gain for feedback-controlling based on the deviation which has been changed based on the adjusting value. Since a prescribed adjusting value corresponding to a deviation is calculated, and the deviation at calculating the target value of torque is changed based on the adjusting value, excessive following after the target value of rotational speed disappears. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
