激光补给无人机跟踪方法研究

激光供能无人机能实现能量实时补给,提升无人机续航时间。无人机一般情况下,飞行距离地面固定补给站较远,激光光斑增大到完全覆盖无人机机身,导致无线能量传输距离过远,以及如何实施激光跟踪瞄准。针对上述问题,本文提出了一种新的跟踪瞄准方法,根据安装在光伏电池板上光敏传感器的输出电压的对比来对无人机进行最优追踪。经计算得出东西向的偏移量为2.310 mm,与实际偏移量2 mm近似,误差0.31 mm。

Research on tracking method of laser supplied UAV

The laser powered UAV can achieve real-time energy supply and enhance the duration of UAV.Usually,UAV flies far from the ground fixed supply station,and the laser spot increases to cover the UAV body completely,which leads to the long distance of wireless energy transmission,and inability to implement laser tracking and aiming.In order to solve the above problems,a new tracking and aiming method is proposed in this paper.According to the comparison of the output voltage of photosensitive sensors installed on photovoltaic panels,the UAV can be tracked optimally.It is calculated that the offset tracking east-west direction is 2.310 mm,which is approximate to the actual offset 2 mm,and the error is 0.31 mm.
