APPARATUS AND METHOD OF POSITION CONTROL FOR SERVO-MOTOR

摘要

a micro processor(10) judging the speed interval of the present servo motor(11) and generating a control signal and increasing the sampling number; an uniform velocity position arithmetic operation part(20) calculating the target position corresponding to the sampling number; the first memory and the second memory reading the corresponding target position in response to the control signal; a PID arithmetic operation part(40) calculating the position error and the gain proportional to the position error; a velocity arithmetic operation part(50) outputting a velocity instruction to control the servo motor; and a counter(14) converting the position information into position data and applying the position data to the PID arithmetic operation part.
