摘　　要：研究了线性不确定系统区域极点与H∞指标约束下的动态输出反馈容错控制器的设计问题。基于连续型执行器故障模式,利用有界实引理和线性矩阵不等式,给出了区域极点指标与H∞指标约束相容性理论及条件,并且分析了区域极点指标相容的H∞指标的取值范围。最后给出了同时满足区域极点与H∞指标约束下的动态输出反馈控制器的设计方法和步骤。仿真示例验证了提出方法的有效性。The problem of dynamic output feedback fault-tolerant controller for linear uncertain systems with regional pole and H~. index constraints is studied. Based on an actuator failure model with continuous gain, the consistency theory and condition between regional pole index and H∞, index are given by using the bounded real lemma and linear matrix inequality, and the ranges of consistent indices are analyzed. At last the design method and steps for the dynamic output feedback controller with consistent index constraints are provided. A simulation experiment shows the effectiveness of the orooosed approach.
