Abstract
Servo control system includes a first repeat control unit for a first servo motor based on a reference angle and a first position error between a swing command and a position of the first servo motor, a multiplication unit which multiplies the swing command by a ratio according to a tilt angle of an inclined surface of a material to be ground to calculate a swing command after multiplication, and a second repeat control unit for a second servo motor based on a reference angle and second position error between the swing command after multiplication and a position of the second servo motor. The first and the second position error are respectively corrected, and driving of the first and the second servo motors are controlled based on the corrected first and second position error, thereby grinding the inclined surface of the material.
