<P>PROBLEM TO BE SOLVED: To provide a motor controller which alleviates a load change at the control time of an object to be controlled, which can remove engaging backlash generated in a mechanism and which can control accurately and stably the object to be controlled. <P>SOLUTION: The motor controller includes: a control quantity set means 13 for setting a target value of the control quantity of the object 12 to be controlled, driven by the motor 11; a drive control quantity calculating means 14 for calculating the drive control quantity from the output of the control quantity set means; a pulse output generating means 15 for generating the pulse of the period shorter than the time constant of the motor; and an adding means 16 for adding the drive control quantity and the pulse output to generate a drive signal for controlling the operation of the object to be controller by finely vibrating the motor within a range without giving an influence to the control quantity of the object to be controlled and to output the drive signal to the motor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
