多任务实时系统仿真软件TrueTime及其应用

TrueTime:A simulation software for multi-tasking real-time systems

本文介绍了一种多任务实时系统仿真软件包TrueTime的组成、功能,并以直流电动机系统的分散控制为例,说明其在网络化控制系统理论仿真研究中的应用。分析表明TrueTime能够仿真多任务实时控制系统的时间特性,可以用来方便地研究网络化控制系统中调度协议对控制系统性能的影响。

This paper presents TrueTime, a simulator for multi-tasking real-time control systems, its application in the simulation of net- worked control systems is shown by an example of a DC servo distributed control system. Analysis and example demonstrate that TrueTime can simulate the temporal behavior of multitasking real-time control systems and can be used to study the effects of network scheduling on control performance in the framework of net-worked control systems.
