본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제 1도는 본 발명의 1실시예를 나타내는 블록도,
제 2도는 보정된 PWM 지령을 출력하는 연산 순서를 나타내는 흐름도,
제 3도는 전류 제어의 타이밍을 나타내는 설명도.

Claims (1)

  1. 마이크로 프로세서에 의해 모터전류를 펄스폭변조(PWM) 제어하는 것으로서, PWM 지령의 연산에 요하는 제어시간의 지연에 의해 생기는 오차량을 보정하는 PWM 제어를 위한 전류 제어장치에 있어서, 소정의 간격에서 디지털치로 변환된 모터 전류치를 읽어 넣는 입력 수단과, 선행하여 읽어 넣어진 모터 전류 정보와 전회의 PWM 지령치에서 결정되는 전류 변화 패턴에 의해 현시점에서의 모터 전류의 변화분을 예측 연산하는 연산수단과, 상기 읽어 넣어진 모터 전류치를 상기 모터 전류의 변화분에 의해 보정하여 PWM 지령을 출력하는 출력수단을 포함하는 것을 특징으로 하는 PWM 제어를 위한 전류 제어장치.
