摘要: 介绍一种基于Matlab/Simulink的联合仿真工具——TrueTime工具箱,利用该工具箱,并以直流电机为对象,建立一个无线网络控制系统的仿真模型。通过对路径损耗函数的研究,得出信号传输的最远距离。仿真实验结果表明,在信号传输的最远距离内,降低节点的发射功率,可实现对无线网络控制系统节点的功率控制。

Abstract: The paper introduces an associated simulation tool——TrueTime tool box, using the tool box builds a simulation model of DC motor in Wireless Network Control System(WNCS). The farthest signal transmission distance is obtained through the investigation of path loss function. Simulation experimental result shows that the node power control of WNCS can be realized by reducing the transmit power within the farthest signal transmission distance.

Key words: Wireless Network Control System(WNCS), TrueTime tool box, path loss, power control
