摘要
为了研究线性时滞不确定系统的鲁棒无源控制问题,针对具有凸多面体不确定线性时滞系统,构造了一个Lyapunov-Krasovskii泛函.利用积分不等式与线性矩阵不等式,给出了系统渐近稳定且严格无源的充分条件;提出了系统状态反馈控制器的设计方法.数值算例说明了所得结论的有效性.
The robust passive control problem of linear time delay systems with uncertainty is investigated.By constructing Lyapunov-Krasovskii functional and using integral inequality and the linear matrix inequality(LMI) technique,a sufficient condition for linear time delay systems with polytopic uncertainty to be asymptotically stable and strictly passive is given,and an approach to design the state feedback controller is proposed.Finally,a numerical example is given to illustrate the effectiveness of the proposed method.
