摘　　要：针对一类中立型时滞互联系统,研究其容错控制问题.设计无记忆反馈控制器,根据李雅普诺夫稳定性理论,结合自由加权矩阵及牛顿-莱布尼茨公式对系统进行稳定性分析,并利用线性矩阵不等式给出当执行器发生故障时,系统仍能保持稳定性的充分条件.数值仿真进一步验证所提控制方法的有效性.The problem of fault-tolerant control is studied for a class of neutral delay interconnected systems.A memoryless state feedback controller is designed,stability analysis of the system base on Lyapunov stability theory,free weighting matrix and Newton-leibniz formula.Sufficient conditions for the system to remain stable when the actuator fails are given by using linear matrix inequalities(LMIs).Numerical simulation example is given to illustrate the feasibility of the proposed method.
