摘　　要：研究一类互联项与弧立子系统均含范数有界不确定性的非线性组合大系统的状态反馈鲁棒分散镇定问题。设计出线性状态反馈鲁棒分散控制器 ,使闭环系统在其平衡点处按指数渐近稳定 ,且鲁棒控制器具有全息结构。最后给出一个数值例子 ,验证了所给结果的有效性。The problem of decentralized state feedback robust control is investigated for a class of uncertain nonlinear interconnected system, in which the uncertainties may appear not only in interconnection but also in isolated subsystem. Each uncertainty is subject to an upper bound on its norm. A type of linear controller with holographic structure is developed. The proposed controllers can ensure that all closed-loop state trajectories exponentially converge to zero. The simulation results show that the method is very effective.
