Abstract:
A method of real-time simulation system is discussed based on synthesizing the benefits of the Simulink/Real-time Workshop(RTW) and the Real-time eXtension(RTX) for Windows. Rapid modeling and encapsulating is implemented by high-powered software and self-defining VC project respectively, which depends on building a Real-time Dynamic Linkable Library(RtDll) composed of model codes generated by RTW. A simulation engine is designed that can load/unload models dynamically and give attention to both decoupling and real-time intercommunication between the model and the engine, which settles for the requirements of transmission model’s input/output information in time and parameter-tuning online. Experiments indicate that the system improves the real-time performance of simulation and gets the identical results as running on Simulink.

摘要： 提出一种综合运用实时工具箱(RTW)与Windows实时扩展子系统(RTX)构建实时仿真系统的方案。采用实时动态链接库(RtDll)形式封装由RTW生成的模型代码，实现由成熟软件快速建模并由自定义VC工程快速封装的模型。根据仿真过程设计可动态加/卸载仿真模型的仿真引擎，兼顾模型与引擎的解耦和实时交互，实现模型输入输出信息的及时传递和模型参数的在线调整。该系统在运行结果与Simulink一致的同时提高了仿真实时性，适用于快速建模与实时仿真实验。
