摘要

半实物仿真是飞行器系统评估与验证的有效技术途径和实验方法。针对某飞行器控制系统实时性、可扩展、高可靠性仿真的需要,给出了由工控机、数字信号处理器、三轴转台、舵机和视景仿真机组成的低成本半实物实时视景仿真系统设计,完成了由飞控仿真模块、运动仿真模块和视景仿真模块等组成的仿真系统软件开发,解决了仿真系统的实时性、数据同步、多结点通信等问题。和飞行试验的对比结果表明,该仿真系统满足了仿真实时性和可靠性要求,对于飞行器研制具有重要的应用价值。
        Hardware-in-the-loop simulation is an effective way and experimental method to evaluate and verify the performance of the aircraft system. To satisfy the requirements of real-time, scalability, high reliability simulation of a certain aircraft control system, a new design of low-cost hardware-in-the-loop real-time scene simulation system consisted of IPC, DSP, three-axis turntable, steering engine and visual simulation computer was put forward. Real-time simulation system software composed by flight control simulation module, aircraft movement simulation module and scene simulation module was implemented,and it resolved the difficulties in real-time, data synchronization, multiple node communication of simulation system. Comparison with flight test results shows that the simulation system satisfied the requirements in real-time and reliability, and it is valuable for aircraft design and research.
