基于PXI的实时仿真测试系统构建技术研究

首先对基于PXI总线控制器的实时系统的构建方法进行分析，在此基础上研究系统平台构建、应用程序开发等，最后通过工程实例-卫星姿轨控仿真系统的开发对上述方法的可行性和有效性进行实验验证。结果表明仿真系统具有定时精度高、开发周期短、系统升级方便等特点，同时还能实现从数学仿真到半物理/物理仿真的无缝升级，可广泛应用于航空航天等众多领域的仿真系统开发。

Research on the Development Technology of Real Time Simulation System Based on PXI Bus

A detailed analysis has been done on the key technology which is about the real time system construction using PXI-Bus controller. At last, an engineering application has been done to validate the feasibility and validity of the research work which is about the satellite GNC simulation system. The experimental result indicates that the real time system has the following characteristic: high timing precision, short developing period, convenience of the system update and so on. It can update seamlessly from the mathematics simulation system to the semi-physics or physics simulation system. It can be applied to develop simulation system in many fields.
