摘　　要：针对复杂模型半实物仿真中每周期耗时接近或超出仿真步长的问题,提出基于多核处理器实现并行仿真从而提高仿真实时性方法。方案关键在于半实物仿真软件的并行化设计思路和实现手段。首先分析运载器串行仿真模型程序与并行仿真模型程序之间的差异;设计一种控制系统实时并行半实物仿真软件架构,采用Vx Works实时操作系统和多核处理器计算机进行实现,同时研制开发相应的实时并行半实物仿真平台。最后,通过半实物仿真验证,在给出半实物仿真结果的同时证明该仿真方法的正确性。并行半实物仿真平台的建立对同类型控制系统半实物仿真具有一定的借鉴意义。In complex model semi-physical simulation in each period, the waste time probably approaches or exceeds the step time. In allusion to this problem, a method of achieving parallel simulation based on multi-core processor is put forward and thus can improve real-time performance. The key issues are the parallelization and implementation of the semi-physical simulation software. Firstly, the differences between sequence model procedures and parallel model procedures are analyzed. Then, a software framework of semi-physical simulation for control system is designed, it is realized based on VxWorks Real-time operating system and Multi-Core processor computer, and the relevant real-time parallel semi-physical simulation platform is developed and carried out. Finally, the semi-physi- cal simulation experimentation is performed, which demonstrates the correctness of the simulation method. The exploitation of this semi-physical simulation platform is significative for this kind of control system semi-physical simulation.
