摘要
针对存在参数不确定性及非线性扰动、传感器或执行器可能失效的一类系统,给出了利用输出反馈使系统能保持渐近稳定的充分条件,并以线性矩阵不等式(LM I)的形式给出,再进一步推广到时滞系统的稳定性问题,以及使系统保持预定特性(圆盘)的充分条件。实例证明了这种方法的有效性和实用性。
For a class of nonlinear systems with parameter uncertainty based on existent literatures, the problem of robust fault-tolerant control for uncertain linear systems with structured parameter perturbation is to be considered. The conditions for the existence of the desired robust fault-tolerant controllers are provided in this paper. As for time-lag system, the condition for the particular feature （ for example disc ） is also presented. It is further shown that this condition is equivalent to the solvability of a certain linear ma- trix inequality（LMI）. A numerical is finally given to illustrate the designing procedure and its simplicity.
