| 中文摘要 |
| 对一类网络控制系统, 研究了变时延和数据丢包对闭环系统稳定性的影响. 基于Lyapunov-Krasovskii方法,给出了闭环系统的稳定条件, 该条件不依赖于时延变化率的上界. 通过求解一个适当的线性矩阵不等式(LMI)得到控制增益矩阵, 求解时不需要对矩阵的结构进行限制, 也不必使用重复迭代. 最后, 给出了一个数值例子以说明方法的有效性. |
| 英文摘要 |
| The stability of networked control systems, subjected to time-varying delay and data-packet-dropout is considered. Based on Lyapunov-Krasovskii approach, new stability criteria, which are irrelevant to the bound of the derivative of the delay, are proposed for the closed-loop systems. The controller gain matrix is obtained by solving a linear matrix inequality (LMI). No constrain is imposed to the matrix structure, and no iterative operation is employed. A numerical example is given to illustrate the effectiveness of the proposed method. |
