基于RTX的无人机飞行剖面实时仿真

Real-time simulation for UAV’s flight profile based on RTX

无人机一般由飞行控制系统控制其在全自主状态下飞行,因此进行无人机的飞行剖面实时仿真变得越来越重要。通过利用matlab/simulink工具搭建无人机飞行控制仿真模型,将预先制订好的飞行剖面任务加载进无人机模型中,运用RTW模块将该飞行控制仿真模型转化成实时环境下的代码。同时针对无人机飞行过程中实时控制的要求,讨论了基于RTX的实时控制方法的设计和实现,并给出了无人机飞行剖面实时仿真曲线。仿真结果验证了仿真的准确性以及良好的实时性。

Real-time simulation for UAV＇s flight profile is becoming increasingly important,because UAV is needed to be controlled in autonomous state generally by its flight control system. Using Matlab/Simulink tool to build a flight control simulation model of UAV, loading pre-established flight profile task into UAV＇s simulation model and converting the flight control simulation model into codes of the real-time environment using RTW module. At the same time,the design and realization of the real-time control method based on RTX arc discussed according to requirements of the real-time control of UAV＇s flight. Experiments of UAV＇ s flight profile are performed and the results show that it runs in high real-time performance and works steadily and reliably.
