【摘要】 介绍一种基于Matlab/Simulink环境的网络控制系统实时仿真工具箱TrueTime2.0。它能够对网络控制系统的网络延时、网络调度、网络参数、控制方法等进行综合的仿真研究,而且与较旧版本的TrueTime工具箱相比有了一定的改进。本文利用TrueTime2.0工具箱搭建网络控制系统仿真平台,结合具体的仿真模型对两种常用的控制网络——以太网和令牌网进行实时仿真研究。通过仿真结果可以看出TrueTime2.0工具箱能够较好地较、方便地实现网络控制系统的仿真,并验证了两种控制网络各自的特点。更多还原

【Abstract】 The paper introduces an ideal simulation tool of networked control systems -TrueTime 2.0 toolbox based on Matlab/Simulink, which can give an synthetic simulation for network delay, network scheduling ,network parameters, control method and so on. By using the TrueTime 2.0 toolbox, a testing platform for networked control systems is proposed, and then, connecting with the concrete examples, the simulation of ethernet network and token ring network is carried out. The simulation results show that this toolbox is an effective tool to realize simulation for networked control systems and the characteristics of control network are verified significantly.更多还原
