| 摘 要： | 本文对弱阻尼特性的卫星姿态的鲁棒控制问题进行了研究。先采用加权办法将对象参数不确定性转化成未建模动态,然后用 H~∞方法进行设计,最后编制了 Safonov 鲁棒稳定裕度k_m 的软件,并对所设计控制系统的鲁棒性能进行了检验和分析。

| Abstract: | In this paper, the robust attitude control of the weak damp satellite with structured uncertainty is investigated. We represent the structrured parameter uncertainty with the unmodelled dynamic uncertainty, and design a mixed sensitivity H-infinity controller. Then, we implement the Sofonov' s Algorithm of the Robust Stability Margin Km on the IBM PC-XT in FORTRAN-LANGUAGE to calculate the robust performance index M. Finally, simulation results and theoretic analysis show, that our control design is valid. |
