| 摘 要： | 研究了具有时变采样周期的网络控制系统在执行器故障时的容错控制器设计问题.首先,将时变采样周期的不确定性转化成系统结构参数的不确定性,建立了时变采样周期网络控制系统的离散模型;在此基础上,设计了状态反馈容错控制器,保持闭环网络控制系统稳定并满足给定的LQR性能指标,该控制器参数通过求解线性矩阵不等式(LMIs)得出.最后,通过实例阐述了上述设计过程,仿真结果证明:此方法是有效的.

| Abstract: | In this paper,the fault tolerant control problem is investigated for a networked control system(NCS) with uncertain sampling period and actuator faults.First,the influence caused by time-varying sampling period is transformed into structured modeling error and the discrete time domain system model is proposed.The purpose of this study is to design a state feedback controller such that,for the variable sampling period and actuator faults,the closed-loop system is stable and satisfies the prescribed LQR perfo... |
