研究无人机自主飞行需要空旷的场地并具有一定的危险性。硬件回路仿真则能够在室内较高地模拟出无人机的实际飞行环境。它可以用来测试硬件的可靠性,系统的整体性能以及调节参数。介绍了一套基于Linux的硬件仿真系统的设计。仿真结果表明该系统具有良好的仿真效果,从而降低了无人机实验的成本并提高了实验效率。 It is dangerous to study unmanned aerial vehicle in open space. Hardware loop simulation is able to simulate the UAV in the room higher than the actual flight environment. It can be used to test hardware reliability, overall system performance, and tuning parameters. Introduced a set of Linux-based hardware simulation system design. Simulation results show that the system has a good simulation results, thus reducing the cost of UAV experiments and improving the experimental efficiency.
