摘　　要：研究一类关联大系统的分散鲁棒容错控制问题。系统中不确定项具有数值界,利用向量Lyapunov函数方法及线性矩阵不等式LMI方法推导了此类系统在传感器失效情况下鲁棒稳定的充分条件,通过求解线性矩阵不等式LMI获得控制器。仿真实例说明了该方法的有效性。The problem of decentralized robust fault-tolerant control is considered for a class uncertain large-scale interconnected systems. The uncertainty in the systems is value-bounded, and a sufficient condition of robust stability was established for the class interconnected systems against sensor failure by using the vector Lyapunov function approach and the linear matrix inequality LMI approach, and the controllers could be obtained by solving the matrix inequalities LMI. The effectiveness of this method was demonstrated with a simulation example.
