无线网络控制系统(WNCS,Wireless Network Control System)具有无需布线、组网和维护方便、易扩展以及良好的移动性等优点,使得无线网络控制系统的分析和设计成为控制界研究的热点之一。针对无线网络控制系统存在的网络时延、丢包、稳定性差的缺陷,着重介绍了一种基于Matlab/Simulink的无线网络系统仿真工具Truetime,通过在Truetime平台下对给定电阻炉温度模型的无线网络进行参数设置、仿真,指导实际无线平台下的温度控制实验,并得到稳定的系统运行。
The analysis and design of wireless network control system becomes a hot topic in the control group because the wireless network control system has the advantages of no wiring,convenient networking and maintenance,convenient scalability and excellent mobility. In view of the deficits of the WNCS,such as network delay, data packet dropout and poor stability, in this paper, a kind of simulation tools of wireless network control system based on Matlab/Simulink is emphatically introduced, the wireless network parameters of the given resistance furnaces model based on the Truetime is simulated and set, then the temperature control experiment conducted on the simulation is performed and the system is operated steadily.
