Abstract

본 발명은 브이 씨 알 및 디 에이 티등의 소프트웨어 서보에 관한 것으로, 위상제어가 정상상태에 도달한 시점에서 위상오차 적분치를 바이어스값에서 감산하거나 가산하여 바이어스 조정장치 없이도 원하는 위상을 빠른속도로 고정시킬 수 있게 한 것이다.The present invention relates to software servos such as V-CAL and DIE, and when the phase control reaches a steady state, subtracts or adds the phase error integral value from the bias value to fix the desired phase at high speed without a bias adjustment device. It was made possible.

Description

드럼의 위상 록크 인 제어방법Phase lock-in control method of drum

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (1)

속도오차와 위상오차값을 확인하여 정상상태이면 바이어스값에 ∫θedt를 더하여 바이어스값으로 정하고, 아니면 현재의 바이어스값을 그대로 채택한 후, “(속도오차×이득)+위상에러에 의한 제어전압+바이어스값”을 제어 전압으로 출력하고, 위상오차가 검출되면, 이 위상오차에 이득을 곱하여 위상오차를 검출하는 것을 특징으로 하는 드럼의 위상 록크 인 제어방법.Check the speed error and phase error value and if it is steady, add ∫θ e dt to the bias value and set it as the bias value, or adopt the current bias value as it is, and then select “(speed error × gain) + control voltage due to phase error. And outputting a + bias value as a control voltage, and detecting the phase error by multiplying the gain by the gain when the phase error is detected. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
