矩阵实验室的仿真工具TrueTime设计

为了便于研究网络控制系统,使用了基于矩阵实验室的功能强大的TrueTime(TT)网络仿真工具箱.它包括网络和计算机两个接口模块,网络模块支持对六种网络的配置;计算机模块具有模拟/数字的转换器,实时内核,网络接口以及外部通道.研究了在矩阵实验室编译环境下利用TT工具箱进行网络控制仿真的方法和流程,主要包括TT工具箱的调用、初始化、编译、控制算法S函数的调用和网络配置方法等.最后给出了两个利用TT工具箱进行网络控制仿真的实例.通过TT进行网络控制仿真能够较好地再现网络控制系统的特征,具有结果可信程度高、易于实现等特点.

Design of matrix laboratory-based TrueTime toolbox

To facilitate the study of network control systems, a matrix laboratory‐based TrueTime （TT） toolbox was adopted, which is a powerful network simulation toolbox. TTincludes network block and computer blocks, the network module supporting six kinds of network configuration, and the computer module consisting of flexible real‐time kernel, analog/digital and digital/analog converter, network interface and an external channel. We studied the method and process of network control simu‐lation using TTtoolbox in matrix laboratory‐based compiler environment, mainly including TTtoolbox call, initialization, compilation, control algorithm of S function call and network configuration method etc.. Finally we provided two simulation examples of network control using TTtoolbox. The results show that the characteristics of network control system are simulated by TTtoolbox, which has high reliability and easy realization.
