中文摘要

对一类满足匹配条件的时变不确定性关联大系统，给出了其可分散状态反馈镇定的充分条件即一组线性矩阵不等式(LMI)有解．在此基础上，通过求解一凸优化问题，指出了具有较小反馈增益的分散稳定化状态反馈控制律的设计方法，文中的仿真示例说明了该方法的有效性和优越性．

英文摘要

For a class of interconnected uncertain systems, which are time-varying and assumed to satisfy the matching conditions, a sufficient condition for decentralized stabilization feedback control laws is presented.This condition is offered as the solvability problem of linear matrix inequalities (LMIs).Based on that, a convex optimization problem with linear matrix in-equality (LMl)constraint is formulated to design a decentralized state feedback control with smaller gain parameters which en-ables the closed-loop system to be asymptotically stable.
