<P>PROBLEM TO BE SOLVED: To provide an accurate position controller without regulating by suppressing a positional deviation occurring at an accelerating or decelerating time of a motor to substantially zero. <P>SOLUTION: The position controller for the motor calculates at least twice to (n) times of incomplete differentiated value of a position command value, obtains a speed command estimated value by multiplying the calculated value by a constant, adds the speed command estimated value to the speed command value output from the controller to be corrected, and inputs a deviation of the speed detected value of the motor from the corrected speed command value to a speed controller so that the differentiated time constant is the same as a primary delay filter time constant. <P>COPYRIGHT: (C)2003,JPO |
