네트워크 제어시스템의 연구 동향 및 무선 NCS 구현 사례

  • Published : 2012.09.25

Abstract

최근 십여년 간 통신 네트워크를 제어시스템에 도입한 네트워크 제어시스템 (Networked Control Systems : NCS)에 대한 연구가 활발히 진행 되고 있다. 이러한 NCS에 대한 최근의 연구동향을 살펴본다. NCS의 정의와 분류, NCS에서 발생하는 지연, 패킷손실, 양자화 오차, 이들을 해결하기 위한 제어기법, 스케줄링 등 여러 NCS와 관련한 제반 사항들의 동향을 살펴본다. 또, 현재 사용되고 있는 무선 네트워크의 종류, 실제로 무선네트워크 제어시스템(Wireless NCS : WNCS)을 구현한 예를 보인다.
