【摘要】 网络控制系统是一种集通信网络和控制系统于一体的全分布式、网络化、实时反馈控制系统,基于Matlab的网络控制仿真工具箱TrueTime为网络控制系统的仿真研究提供了简易可行、功能齐全的工具.TrueTime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,使得网络控制系统的仿真研究更为容易.本文介绍了TrueTime工具箱的组成与功能,结合直流电机网络控制系统实例,给出其TrueTime仿真的具体实现,从仿真结果可以看出TrueTime工具箱对网络控制系统的仿真是有效的.更多还原

【Abstract】 The networked control system is a distributed,networked and real time feedback control system with communication network and control.TrueTime toolbox based on MATLAB provides the tool of simpleness,feasibleness and complete function for the simulation study of the networked control system.Tr-ueTime can take network delays,network parameters,control methods and network scheduling into account together,and implement co-simulation of control performance and network schedule.Consequently,it makes the study of the networked control system be easier.The composing and function of TrueTime is introduced in this paper,in brief.Finally,an example of the networked control system of DC motor using TrueTime is given.The results show the effectivity.更多还原
