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.
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 inequality (LMI)constraint is formulated to design a decentralized state feedback control with smaller gain parameters which enables the closed loop system to be asymptotically stable.
