摘　　要：TrueTime是基于MATLAB/Simulink的网络控制系统仿真工具箱,是目前使用较为广泛的网络控制系统虚拟仿真工具。介绍了一种基于TrueTime的网络控制系统仿真平台,并用基于TrueTime的弹簧-阻尼系统仿真模型为实例,说明该仿真平台的构建方法,同时通过与MATLAB的阶跃响应曲线对比,证明该仿真模型可以很好地模拟网络环境。针对网络控制系统中网络时延和数据包的丢失这两个主要问题,通过对仿真结果的分析,验证网络时延、数据丢包等因素对网络控制系统控制性能的影响。TrueTime is a Networked Control System simulation toolbox based on MATLAB/Simulink, and it is a Networked Control System virtual simulation tool that is widely used. A simulation platform based on Truetime, and explains the construction method through a Spring-Damping System simulation model is introduced, and it is proved that this platform can well simulate network environment comparing with MATLAB step response curve. In view of network delay and data loss, their influence on NCS is verified.
