摘要
研究了具有变时滞的不确定系统的状态观测器和基于观测器的鲁棒控制器设计问题 ,其中不确定性是时变的 ,不要求满足匹配条件 .通过构造增广系统 ,利用线性矩阵不等式( L MI)方法 ,获得了该不确定系统存在状态观测器和基于观测器的鲁棒控制器的充分条件 。
The design of state observer and observer based robust controllers for uncertain linear systems with time varying delays is studied, where the uncertainty is time varying and does not satisfy matching conditions. In the light of the linear matrix inequality(LMI) approach, a sufficient condition is given for the existence of the state observer and observer based robust controllers for such uncertain systems. We obtain state observer and observer based robust controllers by constructing an augmented system.
