摘　　要：针对一类具有常时滞、执行器故障和参数不确定性的关联大系统可靠H∞控制问题,提出了可靠H∞控制器的设计方法,其中参数不确定性满足匹配条件,而执行器故障采取比通常的离散故障模型更实际的连续增益故障模型。本文的目的是设计无记忆分散控制器镇定被控系统。利用线性矩阵不等式获得该控制器,使得系统在此控制器下无论是否发生故障都保持渐近稳定,并且具有一定的H∞性能指标。通过仿真的例子,验证该分散状态反馈控制器的可行性。The problem of reliable H∞ controllers design is considered for a class of uncertain interconnected large-scale systems with constant time delays, parameter uncertainties and actuator faults. Assume that the pa rameter uncertainties satisfy matching conditions and actuator faults are more practical continuous gain model than the common discrete model. The purpose of the paper is to design the linear memoryless state feedback decentralized controllers stabilized system. The controllers can be obtained by solving the linear matrix inequality, which make the control systems be asymptotically stable and H∞ performance whether actuator faults occur. A simulation example is given to illustrate the design of state feedback controllers is effective.
