Abstract

본 발명은 고성능 서보제어가 가능한 타임랩스VCR의 서보장치에 관한 것이다. 본 발명의 장치는 테이프를 소정의 속도로 주행시키는 캡스터모터, 캡스터모터의 회전에 대응하여 발생되는 주파수신호(FG)로부터 테이프 실제 속도와 위치를 측정하는 속도측정부와 위치측정부, 녹화모드에 따른 테이프 위치명령과 실제위치를 비교하여 속도명령을 출력하는 위치제어기, 속도명령과 실제속도를 비교하여 실제속도가 속도명령에 일치하도록 캡스턴모터의 구동신호를 출력하는 속도제어기 및 구동신호에 따라 캡스턴모터를 회전시키는 모터구동부로 구성된다. 따라서, 본 발명은 테이프의 실제위치와 속도를 테이프 위치명령과 속도명령에 정확하게 일치시키는 고성능 서보제어의 효과를 제공한다.The present invention relates to a servo device of a time-lapse VCR capable of high performance servo control. The apparatus of the present invention includes a capster motor for driving a tape at a predetermined speed, a speed measuring unit and a position measuring unit for measuring the actual speed and position of the tape from a frequency signal FG generated in response to the rotation of the capster motor, and recording. Position controller that outputs speed command by comparing tape position command and actual position according to mode, and speed controller and drive signal that output drive signal of capstan motor so that actual speed matches speed command by comparing speed command and actual speed. It is composed of a motor drive unit for rotating the capstan motor. Accordingly, the present invention provides the effect of high performance servo control that accurately matches the actual position and speed of the tape to the tape position command and the speed command.
