摘要
近年来，无人飞行器（UAV）应用领域广泛开发了无线电力传输（WPT）技术。然而，偏差容限一直是无人飞行器无线充电无法解决的问题。本文展示了一种与无人机起落架相连的耦合系统。在设计过程中，设计了一个灵活的弧形线圈，以实现结构利用。首先，计算拱形弯曲线圈的磁感应强度。然后，基于遗传算法的参数优化，提出了不等匝间隔的线圈结构。此外，还进行了三维电磁仿真，以比较优化前后的效果。共振频率为 75 kHz，采用 SS 调谐拓扑结构，符合 Qi 标准。最后，制作了实验装置，结果表明无人机充电系统具有更好的抗偏差能力。
Coupling mechanism optimization to improve misalignment tolerance in UAV wireless charging systems
Wireless power transfer (WPT) technology has been extensively developed for unmanned aerial vehicle (UAV) application in recent years. However, misalignment tolerance has always been an unsolved problem for UAV wireless charging. In this paper, a coupling system attached to UAV landing gear is demonstrated. In the design process, a flexible curved coil has been designed for structure utilization. First, the magnetic induction strength of the arch bending coil is calculated. Then, an unequal turn spaced coil structure is proposed based on the genetic algorithm for parameter optimization. In addition, a 3D EM simulation is implemented for comparison before and after optimization. A resonance frequency of 75 kHz with an SS tuning topology is adopted in accordance with the Qi standard. Finally, the experimental setup is made and the results show that the UAV charging system has better misalignment tolerance.
