| 摘 要： | 为了解决在传输延时、测量的不灵敏性及设备的物理特性等因素产生的时滞问题和建模误差以及系统工作环境变化会带来不确定因素的问题,采用线性矩阵不等式方法,研究一类控制输入时滞和关联时滞均为时变时滞的不确定时滞大系统的鲁棒镇定问题。结果表明:具有数值界表达形式的不确定项,虽然不满足匹配条件,但通过构造Lyapunov泛函,利用Schur补引理,仍可得出其可分散状态反馈镇定的充分条件,最后通过一组数值算例证明了这种方法的有效性。该结果对大系统的分散鲁棒镇定问题具有一定的参考价值和指导意义。

| Abstract: | The paper presents a solution regarding the decentralized robust stabilization problem for a class of uncertain large-scale systems with time-varying and time-delay in both control and conjunction.Based on the representation of uncertainty,the sufficient conditions for decentralized stabilization feedback control are derived using linear matrix inequality techniques.A case study demonstrates the validity and usefulness of the proposed method. |
