<P>PROBLEM TO BE SOLVED: To improve the control characteristics and stability of a recursive controller which is used for reducing the rotation irregularities of a motor rotating at a constant speed. <P>SOLUTION: The recursive controller is used in a motor drive system needing a constant-speed rotation and low rotation irregularities and is mounted with a filter, having a peak at only a specified frequency and capable of adjusting the magnitude of the peak, is used to improve the suppressing effects and stability with respect to the specified frequency. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
