| 摘 要： | 对一类线性不确定系统,研究了区域极点指标、H∞指标和方差指标约束下的容错控制器的设计问题.在更一般、更实际的执行器故障模型下,利用线性矩阵不等式方法,建立了容错控制中三类指标的相容性理论.分析了与区域极点指标相容的H∞指标和方差指标的取值范围,并在相容指标约束下给出了有效的控制器设计方法.仿真实例验证了结果的有效性.

| Abstract: | The problem of reliable system design for linear uncertain systems with circular pole index,steady variance index and H-infinity constraints is discussed.A more practical and general model of actuator failures is adopted.Based on linear matrix inequality approach,the consistency theory on circular pole index,steady variance index and H-infinity constraints is set up,and the ranges of consistent indices are analyzed in detail.Furthermore,the effective controller design method for systems with constrains of consistent indices is provieded.A simulation example shows the effectiveness and necessity of the design method. |
