| 中文摘要 |
| 考虑数据通信时延不确定环境下网络化采样控制系统的稳定性问题. 首先基于输入时滞方法, 建立包含采
样周期信息的网络化采样控制系统的数学模型, 在此基础上, 采用双边闭环函数方法和自由矩阵积分不等式技术,
得到网络传输时滞变化区间依赖稳定性新准则, 并进一步讨论了网络化采样控制系统中网络时延与采样周期之间
的关系. 仿真结果表明减小采周期可以增强网络控制系统对网络通信时延的鲁棒性. |
| 英文摘要 |
| The stability of a class of networked sampled-data control systems with data transmission delay is studied.
Firstly, based on the input delay method, a model of networked control systems with periodic sampling is established. On
this basis, a new stability criterion with uncertain transmission delay is obtained by using the two-sided looped function
method and the free matrix integral inequality technique. Furthermore, the relationship of uncertain data transmission delay
and the sampling period in networked sampled-data control system is investigated. Simulation results show that reducing
the sampling period can improve the robustness of networked control system. |
