Real-Time Workshop实时仿真研究与应用

MATLAB通过组件Simulink提供了一个动态系统建模、仿真和综合分析的集成环境,可以在控制领域中建模并运行仿真,却缺少实时仿真支持.MATLAB工具Real-Time Workshop可以从图形模型生成ANSI C源代码,下载此代码在实时操作系统中运行可以实现实时仿真,但是目前市场上的实时操作系统在开发工具、用户界面等方面存在诸多不足.RTX扩展Windows在提供实时性的同时又可以利用Windows丰富系统资源.利用Real-Time Workshop产生C代码,把要求实时性的代码分离出来放在RTX实时子环境下运行,可以实现实时仿真.实验验证了此方法有较好的实时性.

Research and Application of Real-Time Simulation on Real-Time Workshop

MATLAB provides an environment of system modeling,simulation,and synthetically analyzing via component simulink,and can model and run simulation in field of control.But it lacks the ability of real-time simulation.Real-time Workshop,which is a tool of MATLAB,can generate ANSI C source code which can be downloaded to implement real-time simulation in real-time operation system.But most of the real-time operating systems on market have deficiencies in developing tools and user interface.RTX provides real-time ability by extending the Windows and can also use the resources of Windows.Through separating the code generated form RTW and requesting real-time control,then executing them under the RTSS environment,the function of real-time simulation can be realized.Examples verified the correctness and real-time characteristic of this method.
