Abstract
A position control apparatus and method for controlling a servo motor includes a D/A unit which converts speed command to analog signals, an up/down counter which increases and decreases pulse of encoder based on the rotating direction of a servo motor in either the x or y directions, and a timer periodically generating interrupt signal to a microprocessor. The position control apparatus and method that can control a servo motor by calculating simple linear equation without calculating complicated exponential function if the maximum speed of the servo motor and time required for the servo motor to reach its destination position is furnished to the control system.
