摘要
无人机激光充电相比于太阳光充电,能够提高充电能量功率及改善持续充电性能。自动跟踪瞄准精度是无人机激光充电的关键指标。结合激光充电系统的工作原理及组成部件,分析了无人机激光充电跟踪瞄准精度。通过建立无人机激光充电跟踪瞄准模型,分析了对跟踪瞄准精度产生影响的各项误差因素,以及各单项误差变化分别对方位角和天顶角瞄准综合误差的影响。在此基础上进行合理的误差分配,通过误差综合计算得出激光充电跟踪瞄准的方位角和天顶角综合误差。通过对系统瞄准精度的分析,为后续标定提供了理论参考依据。
Compared with the sunlight charging,unmanned aerial vehicle（UAV）laser charging can improve the power of charging energy and the continuous charging performance.The accuracy of automatic tracking aiming is a key indicator of UAV laser charging.Based on the working principle and components of laser charging system,the precision of laser charging tracking was analyzed.Based on establishing the UAV laser tracking charging model,various error factors affecting the tracking accuracy were analyzed,and the effect of each single error change on the azimuth angle and zenith angle of comprehensive error was analyzed.On the basis of reasonable error distribution,the comprehensive error of azimuth angle and zenith angle of laser tracking charge was obtained.Analysis on the tracking precision can provide theoretical reference for the subsequent calibration.
