Description
Claims (1)
- 모터(6)로부터의 PG 마그네트에 의해 발생한 신호를 TTL레벨로 증폭하는 증폭기(5)와, 상기 증폭기(5)를 통해 출력되는 PG 신호를 비데오 기준 신호와 비교하여 그 위상차에 해당하는 오차 펄스를 만드는 위상 비교부(4)와, 상기 비교기로 부터의 위상 오차에 따른 오차 펄스를 세는 카운터부93)와, 내부 기준신호가 인터럽트를 거는 순간에 상기 카운터부(3)의 값을 읽어서 위상오차를 샘플링 시간인 비데오 기주 펄스의 주기로 나누어서 등가 속도 오차성분을 환산하고 이를 PG 신호와 FG 신호의 주파수비에 해당하는 24로 등분하여 그 각각을 속도오차에 더하여 제어입력을 계산하는 DSP 부(1)를 포함하여 구성한 것을 특징으로 하는 디지탈 브이씨알 서보에서의 위상 검출회로.
