Abstract

XY-스테이지용 위치 제어 장치가 개시된다.A position control device for an XY-stage is disclosed.

본 발명은 XY-스테이지 시스템을 전체적으로 제어하는 CPU와, 상기 CPU로부터 전송받은 XY-스테니지의 현재위치와 목표위치와의 위치 오차 데이타를 소정 신호로 변환하여 출력하는 위치 오차 변환부와, 상기 위치 오차 변환부로부터 출력된 신호를 입력받아 비례, 적분 및 미분제어를 수행하는 PID 제어부와, 상기 XY-스테이지의 가감속 구간에서 발생되는 실제적인 위치 오차를 보상해주기 위한 위치 오차 보상부와, 상기 XY-스테이지의 목표 위치량을 정현파 값으로 변환하여 출력하는 정현파 변환부와, 상기 정현파 변환부로부터의 신호를 입력받아 상기 XY-스테이지의 모터를 구동시키는 모터 드라이버를 구비한다.A position error converting unit for converting position error data between a current position and a target position of the XY-stage transmitted from the CPU into a predetermined signal and outputting the predetermined signal; A position error compensator for compensating an actual position error generated in the acceleration / deceleration section of the XY-stage, a position error compensator for compensating an actual position error generated in the acceleration / deceleration section of the XY-stage, A sinusoidal wave conversion unit for converting the target position amount of the stage into a sinusoidal wave value and outputting the sinusoidal wave value; and a motor driver for receiving the signal from the sinusoidal wave conversion unit and driving the motor of the XY-stage.

이와 같은 본 발명에 의하면, 위치 오차 보상부에 의해 구동 모터의 가감속 구간에서 발생하는 실제적인 위치 오차를 신속히 보상하여 제어에 반영하므로 고정밀도의 위치 제어가 가능해 진다.According to the present invention, the position error compensator compensates for the actual position error occurring in the acceleration / deceleration section of the driving motor quickly and is reflected in the control, so that it is possible to perform the position control with high accuracy.
