【摘要】 无人直升机是一个极具挑战性的多学科前沿性研究课题。介绍了小型直升机LINUX仿真系统的构建过程及其相关软件实现。首先给出了小型直升机飞行控制系统和仿真系统的整体结构,并针对这两个系统结构做了简要说明。介绍了在LINUX平台下,采用FLTK图形界面库和Mesa/OpenGL实现小型直升机3D飞行和状态控制,可视化仿真及实时运动特性再现的过程。仿真系统的结果表明,仿真系统具有独特的优点和良好的开发潜力,可以辅助实际飞行实验进行无人直升机的研究。更多还原

【Abstract】 Unmanned helicopter is a very challenging multi-subject forefront research topic.We introduced the building process of the simulation system based on LINUX for small-scale helicopter and the related software implementation.First we provided the overall structures of both flight control system and the simulation system of small-scale helicopter,and made a brief description for the two system structures.We also introduced that we used the FLTK graphical interface library and Mesa/OpenGL to achieve the 3D fight,attitude control,visual simulation and the reproduction process of real-time motion characteristics of the small-scale helicopter on LINUX platform.The result of the simulation system indicates that the simulation system has unique advantages and favorable exploitation potential.It may help the actual flight experiments of unmanned helicopter research.更多还原
