| 摘 要： | 对于线性系统,研究了考虑传感器故障的圆盘极点可靠控制设计问题.使用了比离散故障模型更实用和一般的连续故障模型,给出了将极点可靠配置在指定圆盘内可靠控制存在的充分条件.通过求解线性矩阵不等式完成动态输出反馈可靠控制器的设计.仿真例子不仅说明了可靠控制的有效性,而且说明了可靠配置的必要性.

| Abstract: | The reliable design of disk pole placement against sensor failure is investigated for linear systems.A continuous model of sensor actuator failure is presented,which is more practical and general than discrete models.A sufficient condition is given to control the reliable pole placement in a definite disk.Dynamic output feedback controller is thus designed by solving LMI(linear matrix inequality).A simulation example shows the effectiveness and necessity of such a reliable placement. |
