摘要
讨论了离散线性系统的鲁棒容错控制问题。针对离散线性系统,当存在范数有界参数摄动时,通过Lyapunov稳定性理论给出了系统同时存在执行器失效情况下的鲁棒稳定的充分条件,并将该条件转化成了线性矩阵不等式的可解性问题。最后用数值算例解释了该算法的有效性。
The robust fault-tolerant control problem of linear discrete system is discussed in this paper. A sufficient condition of robust stability for discrete system under norm bounded perturbations with actuator failures is presented by employing Lyapunov method, and it is further shown that this condition is equivalent to the solvability of a certain linear matrix inequality(LMI). A numerical example is also given to illustrate the designing procedure and its simplicity.
