摘　　要：针对具有执行器故障的Delta算子不确定系统在圆形区域极点配置下的H∞可靠控制问题,设计了一个可靠控制器,使得Delta算子系统能够同时满足区域极点约束和H∞性能约束。在考虑更一般、更实际的执行器连续故障模型的基础上,利用线性矩阵不等式(LMI),给出了在区域极点约束下Delta算子不确定系统H∞可靠控制器的存在条件。数值仿真表明了该方法的可行性。The H∞ reliable control problem is considered for the delta operator formulated uncertain systems with actuator failure and regional pole assignment.The purpose is to design a reliable controller such that the delta operator closed-loop poles systems can simultaneously satisfy regional pole constraints and H∞ performance constraints.Based on a more practical and general actuator failure model which is called continuous failure model,the existence condition of the H∞ reliable controller for the delta operator uncertain systems with regional pole constraints is given via the linear matrix inequality（LMI） approach.A numerical simulation shows the availability of the proposed method.
