针对一类带有不匹配不确定性的奇异时滞系统，建立了基于观测器状态的滑模面和滑模控制器。采用等价控制方法获得滑模运动系统，给出了其在滑模面上正则、无脉冲模、渐近稳定的充分条件。滑模面及控制器的解可通过锥补迭代算法求解矩阵不等式获得。给出了一个仿真实例验证理论的有效性。

A variable structure control based on the states of observer was proposed for a class of uncertain singular time-delay systems with mismatched unstructured uncertainties. By using the equivalent control approach, the sliding mode dynamics was given. The sufficient condition was introduced such that the sliding mode dynamics is regular, im-pulse-free, and asymptotically stable. The sliding surface and the controller’ s parameterization was obtained by sloving matrix inequlities via cone complementary linearizable iterative algorithm. The numerical simulation provides evidence for its effectiveness and efficiency.
