摘　　要：针对带有非线性不确定参数的线性时滞系统鲁棒稳定性问题,讨论了一种带有二次不确定参数的状态空间模型,对该系统进行鲁棒稳定性分析.所得结果与时滞相关,且对于不确定性参数满足广义匹配条件情形,相应结果以线性矩阵不等式的形式给出.The problem of robust stability for linear time-delay systems with nonlinear uncertain parameters is studied. A new uncertain state-space model with second-order uncertain parameters is proposed and the robust stability of the system is analyzed. When the uncertain parameter is satisfied the generalized matching condition, the result is delay dependent and given in terms of linear matrix inequalities.
