中文摘要
      研究了一类线性不确定离散时滞系统的H∞鲁棒控制问题,其时变不确定项是范数有界的,但无需满足匹配条件.基于线性矩阵不等式 (LMI)方法,得到了可H∞鲁棒镇定的一个充分条件.通过求解一个特定的线性矩阵不等式,即可获得H∞状态反馈控制器.具体算例说明了该方法的有效性.
英文摘要
      The problem of H-infinity robust control for a class of linear uncertain discrete time-delay systems is studied. The time-varying uncertainties are assumed to be norm-bounded and requires no matching condition. Based on linear matrix inequalities (LMI) approach, a sufficient condition for the systems to be H-infinity stabilizable is presented. By solving a certain linear matrix inequality, the H-infinity state feedback controllers are obtained. A numeric example is given to demonstrate the effectiveness of the method.
