摘　　要：考虑了一类关联大系统的可靠控制器设计问题,该系统具有常时滞、参数不确定性和传感器故障.其中参数不确定性满足匹配条件,传感器具有部分失效的模型.目的是设计无记忆分散控制器来镇定该系统.通过解线性矩阵不等式获得此控制器,使得当传感器器发生故障时被控系统能够保持渐近稳定.最后通过仿真的例子,验证该状态反馈控制器的可行性.The problem of reliable controller design was considered for a class of uncertain interconnected large-scale systems with constant time delays and parameter uncertainties. The parameter uncertainties satisfy matching conditions, and sensor fault was considered for part-disable. The purpose of the paper was to design linear memoryless state feedback decentralized controllers to stabilize the systems. By solving the LMI, we get the controllers which make the systems be asymptotically stable when sensors experience failures. At last a simulation example is presented to show that the state feedback controllers are effective.
