Abstract

본 발명은 광자기 디스크 드라이브의 구동제어계에 관한 것으로, 지령위치에서 측정위치를 감산하여 위치오차를 출력하는 위치오차 산출기와, 위치오차를 입력하여 소정 오차보다 크면 소정크기로 포화시키고, 작으면 선형제어따라 위치를 제오하며 이에 따른 지령속도를 출력하는 위치제어기와, 지령속도에서 측정속도를 감산하여 속도오차를 산출하는 속도오차 산출기와 속도오차를 입력하여 속도를 제어하는 속도제어기와 속도제어기의 출력을 검출하여 측정속도를 산출하는 속도측정부와 속도측정부의 출력을 입력하여 측정위치를 산출하는 위치측정부를 구비하여 억세스속도를 향상시킨다.The present invention relates to a drive control system for a magneto-optical disk drive, comprising: a position error calculator for subtracting a measurement position from a command position and outputting a position error; Position controller outputting the command speed according to the control and outputting the command speed, speed error calculator for calculating the speed error by subtracting the measured speed from the command speed, speed controller for controlling the speed by inputting the speed error, and output of the speed controller. It is provided with a speed measuring unit for detecting the speed and calculating the measurement speed and a position measuring unit for calculating the measurement position by inputting the output of the speed measuring unit to improve the access speed.
