HLA在半实物仿真系统中的应用研究

Application of HLA framework in hardware-in-the-loop simulation system

半实物仿真是分布式仿真领域的一个关键组成部分,它最鲜明的特点就是要求具有实时性。然而HLA虽然在顶层设计时预留了仿真接口,但目前的HLA系统在实时仿真的成效却达不到半实物仿真的需求,因此提高HLA系统的实时性是分布式仿真系统需要解决的一个关键技术。首先,介绍了HLA定义、对象模型模板、运行支撑系统接口RTI,阐述了HLA互操作性和重用性应用于半实物仿真系统中的重要作用;然后,提出了HLA应用于半实物仿真系统内部和半实物仿真与其它仿真互联系统时,从不同层面提高仿真系统实时性的方式;最后,给出了使用HLA工具对某半实物仿真系统进行搭建的方法。

Hardware-in-the-loop simulation is an important component of distributed simulation, and its main feature is the requirement of hard real-time. However, although the HLA has been designed at the beginning of the design of real-time simulation interface, but the current performance of the HLA system in real-time performance of less than half-physical simulation of real-time requirements, so improve the real-time HLA system is distributed simulation field A research hotspot. Firstly, the HLA definition, object model template and run support system interface RTI are introduced, and the important role of HLA interoperability and reusability in the hardware-in-the-loop simulation system is described. Then, HLA is applied to the interior and semi-Hardware simulation and other simulation of the interconnection system, from different levels to improve the realtime simulation system;Finally, a method of designing a semi-physical simulation system by using HLA object model is given.
