  • 摘要: 讨论基于FMMⅡ模型的具有状态饱和的一类二维(2-D)离散不确定时滞系统的鲁棒稳定性分析问题. 采用Lyapunov方法,分析了具有状态饱和的2-D离散时滞系统的渐近稳定性,给出了其稳定性判据. 在此基础上,给出了2-D离散不确定时滞系统鲁棒稳定的判据. 以上结果均为线性矩阵不等式(LMIs) 形式,易于在实际问题中应用. 数值算例说明了该判据的有效性.

     

    Abstract: In this paper, we address the problem of robust stability analysis of 2-D discrete uncertain systems described by the Fornasini-Marchesini second local state-space model (FMMⅡ) with shift-delays employing state saturation. By utilizing the Lyapunov method, first, a sufficient condition for 2-D discrete delayed systems to be stable is presented. Next, a sufficient criterion for 2-D discrete uncertain delayed systems to be robustly stable is obtained. All of results are expressed in terms of linear matrix inequalities (LMIs). An example is given to show the effectiveness of present criteria.
