Abstract

In this paper, a stabilized control algorithm for the large rotating stand of a long-range surveillance radar (LRSR) system is introduced. The stabilized control algorithm for this large rotating stand system was designed using mathematical plant modeling. The LRSR system is located on high ground and has a wide surface, making it susceptible to the effects of wind, which increases the bearing friction and reduces the stability of the rotating stand. The disturbance caused by the wind was analyzed using computational fluid dynamics (CFD) in this study. The results of the CFD analysis were used to construct a control algorithm for the disturbance . The performance of the proposed control algorithm was demonstrated experimentally and through simulations. The plant model and the control algorithm were constructed in Matlab/Simulink.

본 논문은 장거리 탐지 레이더(LRSR;Long Range Surveillance Radar) 회전 구동 안정화에 관한 내용으로, 외란에 강인한 제어기 설계에 관한 것이다. 외란에 강인한 제어기 설계를 위하여 시스템 동특성과 외란 요소를 분석하고 그에 대한 수학적 모델링을 수행한다. 탐지레이더는 바람이 강한 높은 지대에 설치되는 특성과 넓은 안테나면을 갖는 형상적인 특성을 감안하였을 때 주 외란 요소는 풍속을 들 수 있다. 풍속은 베어링의 마찰을 증가시키는 요소로 작용하고 이는 안정화 성능을 저해 한다. 풍속이 탐지레이더에 미치는 영향은 전산유체역학(CFD;Computational Fluid Dynamics) 해석 결과를 이용한다. 전산유체역학 해석 결과를 제어알고리즘의 외란 입력으로 구성하여 제어기법에 대한 안정화 성능을 시뮬레이션과 실험을 통하여 기술한다. 플랜트 모델링 및 제어기는 Matlab / Simulink 를 이용하여 구성한다.
