| 摘 要： | 针对短时延网络控制系统,提出了将时变采样周期分成为定常采样周期和网络诱导时延的和.建立了系统离散模型,将采样周期的不确定性转换成系统参数的不确定性.研究设计了最优保性能状态反馈控制器,基于线性矩阵不等式的可行解给出了控制器参数.仿真证明了该方法的有效性,比较于其他的设计方式,该方法的计算量小.

| Abstract: | This paper considers the networked control systems(NCS) with the varying sampling period.For linear time-invariant controlled plant,under the assumption that the time delay is constant and shorter than the sampling period,the sampling is time-varying within a certain known bound.The system is transformed into a time-varying discrete time system,where the time-varying sampling period parts are treated as norm bounded uncertainties of the structure parameter.Linear matrix inequality(LMI)-based static sate-fee... |
