基于MATLAB和FLIGHTGEAR的可视化飞行仿真

摘要

The control law was designed by using the aerodynamics datum which is estimated by the U.S. Air Force DATCOM, and then dynamic simulation was performed through the combination of MATLAB and FLIGHTGEAR. The design drawback of flight control system could be easily checked for the datum of the full simulation process was displayed by 3D visualization mode in real-time. The design can be simplified, development time and cost can be reduced by using FLIGHTGEAR open software, it is suitable for the check of early aircraft design, and reduces the project iteration.%利用美国空军气动估算软件DATCOM中得到的气动数据，进行了控制律的设计，并通过MATLAB结合飞行模拟软件FLIGHTGEAR进行了动态仿真。仿真试验全程数据以直观的实时三维视觉仿真方式显示，有利于发现飞行控制系统设计缺陷。利用现有开放软件的仿真可以简化设计、缩短开发周期，同时还大大降低了成本，非常适合飞机早期设计验证，以减少后期设计迭代。
