摘要
针对时变多状态滞后不确定线性系统 ,研究了状态反馈保性能控制律的设计问题 ,采用线性矩阵不等式方法 ,导出了保性能控制律的存在条件和参数化表示。通过求解一个线性矩阵不等式约束的凸优化问题 。
In this paper, the problems of designing state feedback guaranteed cost control laws are studied for a class of uncertain linear systems with time\|varying multi\|state delay and subject to norm\|bounded parameter uncertainty. By using the linear matrix inequality approach, the existence conditions are derived and a parameterized representation of the guaranteed cost controllers is presented. Furthermore, a convex optimization problem with LMI constraints is formulated to design the optimal guaranteed cost controllers.
