基于TrueTime的网络控制系统实时仿真

Real-time Simulation of Networked Control System Based on TrueTime

网络控制系统是涉及控制系统与通信网络的复杂系统,其仿真过程需要综合考虑多方面因素。引入了网络控制系统理想的仿真平台——TrueTime工具箱,可以对网络时延、网络参数、控制方法、网络调度等多方面进行综合仿真研究,实现控制性能与网络调度同时仿真的要求,从而使得网络控制系统的研究更加容易。结合实例,利用TrueTime仿真平台实现了对网络控制系统的实时仿真,仿真结果可以看出TrueTime工具箱对网络控制系统的实时仿真的有效性。

Networked control system （NCS） is a complicate system that relates to the question of real time control and network scheduling, its simulation should take networked delays, network parameters, control methods and network scheduling into account together. An ideal simulation platform of NCS-TrueTime toolbox is introduce, it implements co-simulation of control performance and network schedule. Finally, a real-time simulation example of NCS using TrueTime is given, results show the effectivity.
