| 中文摘要:针对一类不确定线性系统，基于线性矩阵不等式（LMI），给出状态反馈鲁棒控制器的设计算法。利用比离散故障模型更具有实际意义的连续故障模型，给出确定状态反馈鲁棒可靠控制器存在的充分条件，通过求解LMI，确定鲁棒可靠控制器的参数矩阵。所给出的鲁棒可靠控制器，不仅可以保持不确定闭环系统的极点保持在圆盘内，而且能够抵御执行器故障对圆盘极点的影响。一个数值例子说明所给出方法的有效性及可行性。 |

| Abstract:For a class of uncertain linear systems, we present an LMI (Linear Matrix Inequality) based approach to design a state-feedback robust reliable controller .A more practical continuous model of sensor and actuator failures than discrete model is considered, we present the sufficient condition for existence of the state feedback robust reliable controller. By solving the LMI, determine the parameter matrix of the robust reliable controller. The robust reliable controller given ,not only can keep poles of the uncertain closed-loop system in expected disk, but also can against the influence of actuator failures for the disk poles. A numerical example is given to show the effectiveness and the feasibility of the obtained results. |
