분산 제어 시스템에서의 시간 지연 보상을 위한 2-자유도 μ 제어기 연구에 관한 연구

Abstract

In the distributed control systems where the control components, controllers and sensors are distributed on a communications network, there exit network time delays on communication lines between the system components. This paper deals with the 2 D.O.F. ramp tracking controller design issue for such system. Time delay terms are converted into rational terms using Fade approximation method and the system is augmented with two integrators for ramp tracking. For this system, li-controller design method, which enables to meet not only performance requirements but robust stabilities simultaneously, is employed.
