Abstract

본 발명에 따르면, DC 모터의 회전에 따라 슬리브가 개폐되어 유량이 조절되는 DC 모터를 이용한 유량제어 밸브의 다단제어 방법에 있어서, 상기 DC 모터에 인가되는 구동전압에 따라 정해지는 DC 모터의 각속도값을 단계별로 스케줄링할 수 있도록 복수 개의 한계값(SP1, SP2, SP3, SP4...)을 기준으로 상기 DC 모터의 단계별 각속도 제한 영역을 구획하며, 하나의 각속도 제한 영역 내에서 해당하는 DC 모터의 각속도 지령(Sn)에 따라 DC 모터가 정해진 각속도값으로 회전하도록 제어하되, DC 모터의 각속도값이 해당 각속도 제한 영역의 한계값(SPn)을 벗어나게 되면, 다음 단계의 각속도 제한 영역 내에서 해당하는 DC 모터의 각속도 지령(Sn+1)에 따라 DC 모터가 해당 제한 영역의 한계값(SPn+1)을 벗어날 때까지 정해진 각속도값으로 회전하도록 제어하는 것을 특징으로 유량제어 밸브의 다단제어 방법이 제공된다.
