摘要：
建立时滞差分不等式，得到网络化控制系统(NCS)的指数稳定判据，基于该判据设计NCS状态反馈控制器。该设计以线性矩阵不等式(LMI)形式给出，不包含任何自由矩阵，通过Matlab中的LMI工具箱进行求解。数值仿真结果表明，该设计具有计算量小、求解方便、保守性弱的特点。

Abstract:
This paper obtains an exponential stability criterion of Networked Control System(NCS) by constructing a delayed difference inequality. On the basis of this new established criterion, it designs a feedback controller in the form of Linear Matrix Inequality(LMI). It does not contain any free-weighting matrices, and can be solved by LMI toolbox in Matlab software. Numerical value simulation result shows that this design has less computational complexity and conservatism, and it is convenient to implement.
