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。
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.
