摘　　要：针对不确定变时滞广义系统的可靠控制问题进行研究.基于积分不等式,用线性矩阵不等式给出了状态反馈控制器的设计方法,保证了在执行器允许的失效范围内闭环系统正则、无脉冲且稳定。所有得到的结果都以严格的线性矩阵不等式给出,没有涉及到系统矩阵的分解.此外,用数值算例表明了所采用方法的有效性和实用性。This paper deals with the reliable control for uncertain singular systems with time- varying delay. Based on integral inequality, an linear matrix inequality （LMI）approach is developed to design desired state feedback controllers, such that the closed-loop system is regular, impulse free and stable for all admissible actuator failures. All the obtained results are formulated by strict LMI involving no decomposition of the system matrices. Furthermore, numerical examples are given to demonstrate effectiveness and applicability of the proposed methods.
