Flight Control System of Unmanned Aerial Vehicle

To date unmanned aerial system(UAS)technologies have attracted more and more attention from countries in the world.Unmanned aerial vehicles(UAVs)play an important role in reconnaissance,surveillance,and target tracking within military and civil fields.Here one briefly introduces the development of UAVs,and reviews its various subsystems including autopilot,ground station,mission planning and management subsystem,navigation system and so on.Furthermore,an overview is provided for advanced design methods of UAVs control system,including the linear feedback control,adaptive and nonlinear control,and intelligent control techniques.Finally,the future of UAVs flight control techniques is forecasted.     

折叠翼无人机火箭助推发射过程影响因素分析与仿真

为深入分析无人机火箭助推发射过程,针对双发火箭在无人机机体上安装位置误差引起的额外力矩和无人机机翼展开时间对无人机飞行存在较大影响这一问题,本文建立无人机非线性模型和控制系统。采用变量法简单明确地进行分析,确定了安装位置误差的边界值和合适的机翼展开时间段。仿真结果表明,得到的边界值和展开时间段满足实际飞行要求。
