<P>PROBLEM TO BE SOLVED: To achieve motor drive control for stably rotating a driven object by enabling generation of a stable speed control signal by hardly causing oscillation at the time of feedback control. <P>SOLUTION: The motor drive control device 10 for controlling a rotational speed of a motor includes: a motor driver 11 for rotationally driving a motor 12; a correction coefficient calculating unit 71 for detecting a rotational speed of an output of the motor 12 on the basis of an alternate current signal outputted from an FG sensor 13 and detecting a rotational position of a photoconductive drum 43, which is rotated by a rotational drive force of the motor 12, on the basis of a pulse outputted from an encoder 15; and a speed control section 72 for generating a speed control signal corresponding to a total correction amount, which is a sum of a correction amount calculated in the correction coefficient calculating unit 71 based on a rotational speed of the motor 12 and a correction amount calculated based on a rotational position of the photoconductive drum 43, and outputting the generated speed control signal to the motor driver 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
