A study on the ramp tracking controller for the Distributed Control Systems with Network-Induced Time Delays by $\mu$-control

$\mu$ 제어에 의한 네트웍의 시간 지연이 존재하는 분산제어시스템의 램프추종 제어기 설계에 관한 연구

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