<P>PROBLEM TO BE SOLVED: To provide a rotator driving control method and a recording medium capable of exactly controlling a fluctuation due to an error in a power transmission system, satisfying robust control performance, keeping high stability even under a fluctuation, and satisfying control performance; and to provide an image forming device and an image reader capable of constructing a highly accurate rotator driving control method which can exhibit required performance under the presence of variance between individuals and always obtaining images with high quality. <P>SOLUTION: In the rotator driving control method, the rotation of the rotator 105 is driven through power transmission systems 1503, 1504 by a motor 1501, detects an angular displacement of a shaft of the rotator 1505 is detected, follow-up control is conducted for the motor 1501 so as to obtain a targeted angle displacement, a feedback controller is designed to satisfy the robust control performance, and the above control is conducted with the feedback controller. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
