Abstract

본 발명은 디지탈 브이씨알의 드럼 모터 및 캡스턴 모터 제어방법에 관한 것으로, 종래에는 드럼 모터와 캡스턴 모터의 구동시키기 위해 속도 제어 루프와 위상 제어 루프가 각기 접속되어 궤환 루프를 형성하도록 구현되어 있음으로 서보계 설계가 복잡해질 뿐만 아니라 시스템의 구현이 어려워지는 문제점이 있었다.The present invention relates to a method of controlling a drum motor and a capstan motor of a digital BC. In the related art, a speed control loop and a phase control loop are connected to each other to form a feedback loop for driving a drum motor and a capstan motor. Not only did the system design become complicated, but the system was difficult to implement.

이러한 점을 감안하여 본 발명에서는 하나의 칩에 속도 제어 루프와 위상 제어 루프를 구현하고, 속도오차와 위상오차에 따른 속도오차를 연산함에 따라 드럼 모터와 캡스턴 모터를 제어함으로써 각기 하나의 제어회로를 갖게 구성한다. 이에따라 서보계의 설계가 간편해진다.In view of the above, the present invention implements a speed control loop and a phase control loop on one chip, and controls a drum motor and a capstan motor by calculating a speed error according to the speed error and the phase error. Configure to have. This simplifies the design of the servo system.
