<p>Method and apparatus for controlling an operating speed of a motor (35) provided to move an object body such as a carriage (31) carrying a printing head (30) in a printer, wherein a control-signal generating portion (70, 70a, 70b) generates a control signal for controlling the speed of the motor such that a moving speed of the object body represented by a speed signal generated by a speed-signal generating portion (39, 63, 64) coincides with a target value, and the control signal is generated on the basis of proportional and integral control values obtained on the basis of an output of a filter (11, 11a) operable to remove from the speed signal at least a component corresponding to a predetermined frequency of the motor, and a differential control value obtained on the basis of the output of the filter or the speed signal. <IMAGE></p> |
