为了满足对无人机飞控系统有效性验证的需求,设计一种基于嵌入式PC104平台、QNX实时操作系统的通用半物理仿真系统.介绍了半物理仿真系统的硬件、软件和系统处理流程,分析了各个结构的模型设计,并对仿真机的软、硬件进行重新设计.分析结果表明:该系统不仅可对直升机飞控进行仿真,也可对定翼机飞控进行仿真,满足飞控的实时仿真需求,并已在多款无人机型号上得到实际验证.%In order to meet the requirements of unmanned air vehicle (UAV) flight control system validation, design a kind of general semi-physical flight simulation system based on embedded PC104 platform and the QNX real-time operating system. Introduces the hardware, software and system process of semi-physical flight simulation system, analyzes the model design of each structure, and redesign the hardware and software of the simulation computer. The analysis results show that the system not only can be simulated for helicopter's flight control, can also be simulated for fixed wing's flight control, meet the requirements of real time flight control simulation, and has been validated on a variety of actual UAV models.
