中文摘要：
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.
英文摘要：
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-feedback controller is proposed;and the cost guaranteed performance control of the system is studied.A numerical simulation results show the validity of the proposed method.Compared with other methods,the major advantage of this method is easy in compatation and consistent with the practical NCS.
