摘　　要：为了在不同网络情况下对NCS性能进行比较,并且能够方便控制算法研究,建立了功能完善的网络控制系统(NCS)平台。对Matlab/TrueTime主要特点进行了分析,并利用其核心模块和网络模块,建立了一种NCS仿真模型;详细介绍了基于TrueTime网络仿真环境下NCS仿真模型的构建方法,并针对网络传输中出现的问题进行了实验研究和全面分析,对NCS的时延和丢包实验进行了深入地分析。实验结果表明该平台为NCS研究提供了便捷的途径。To compare the performance of NCS under different network situations, and make the study of control algorithms easier, the networked control system （ NCS ） platform with comprehensive functions is established. The main features of Matlab/TrueTime are analyzed, and a NCS simulation model is established by adopting the kernel and network module of Matlab/TrueTime. The method of how to establish the simulated model of NCS based on TrueTime network simulation environment is introdced in detail, and the problems occurred in network transmission are researched by experiments and analyzed comprehensively. The experiments of time delay and packets loss experiments in NCS are analyzed in detail. The experimental result indicates that this platform provides easy and rapid path of researching NCS.
