中文摘要：

现在，越来越多的地设备通过象 fieldbus 或工业以太网那样的一个连续通讯网络被连接到中央控制器。一些象控制器区域网络(罐头) 或工业以太网一样的这些连续通讯网络将介绍随机的转移延期进联网的控制系统(NCS ) ，它引起控制性能降级甚至系统不稳定性。处理这个问题，适应预兆的功能的控制算法被与可变延期把预兆的功能的控制的概念用于一个分离州的空间模型导出。估计导致网络的延期的方法也被建议便于实现的控制算法。然后， NCS 模拟研究基于 TrueTime 模拟器被执行验证建议控制算法。数字模拟证明建议适应预兆的功能的控制算法为有随机的延期的 NCS 是有效的。

英文摘要：

Nowadays, more and more field devices are connected to the central controller through a serial communication network such as fieldbus or industrial Ethernet. Some of these serial communication networks like controller area network （CAN） or industrial Ethernet will introduce random transfer delays into the networked control systems （NCS）, which causes control performance degradation and even system instability. To address this problem, the adaptive predictive functional control algorithm is derived by applying the concept of predictive functional control to a discrete state space model with variable delay. The method of estimating the networkinduced delay is also proposed to facilitate the control algorithm implementing. Then, an NCS simulation research based on TrueTime simulator is carried out to validate the proposed control algorithm. The numerical simulations show that the proposed adaptive predictive functional control algorithm is effective for NCS with random delays.
