| 摘 要： | 针对网络控制系统中普遍存在的网络诱导时延和数据包丢失问题,在考虑模型中存在噪声和数据包时序错乱的情况下,利用网络控制理论,分析系统具有网络诱导时延和数据包丢失的特性.基于一定的数据包丢失率和随机时延,系统被建模为由结构事件率约束的异步动态切换系统.通过算例验证方法的有效性,该成果对研究NCS具有重要意义. |

| Abstract: | For Networked Control System in the presence of the network-induced delay and packet dropout,where white noise with zero mean and time order-messed data packet are considered.We utilize networked control theory and analyze the peculiarity in this kind of system and based on fixed data packet dropout rates and stochastic network-induced delay,the NCS is modeled as an asynchronous dynamical-switched system constrained by configuration event rates.A example shows that the method is valid and the result is very important to study NCS. |
