Design and Realization of Real-Time Flight Testing System Based on VeriStand

摘要:

针对飞行器改装带来的实时模飞测试问题,提出了一种实时飞行测试系统设计及实现方案。首先分析了待测飞控及安控系统的工作过程和技术特性,给出了实时测试系统应该具备的功能。基于功能需求,明确了系统采用PC上位机-PXI实时下位机的硬件架构,同时给出了上位机、下位机的硬件资源配置。系统采用VeriStand、MathWorks Simulink?、LabVIEW分别完成实时测试项目配置与管理、实时模型开发、虚拟串口设备驱动开发任务,并详细讨论了实时模型和虚拟串口设备驱动的开发过程。最后分析了实时测试结果。

Abstract:

In order to solve the problem of real-time flight simulation test of the modified vehicle, a design and realization scheme of real-time flight test system was proposed in this paper. The working process and technical features of flight control system and safety control system that would be tested was analyzed firstly and the function of the real-time test system was listed. Based on the function demand, the hardware structure was suggested that the system should be composed by PC and PXI real- time computer, at the same time, the hardware resource was advised. The configuration and management of real-time test project, the software of real-time model, the diver software of the dummy series interface equipment in the system was respectively developed by VeriStand, MathWorks Simulink?, LabVIEW, the development process of the real-time model software and the dummy series interface equipment software was discussed detailedly. The real-time test results was analyzed finally.
