    摘要:

    无线电能传输技术在无人机领域应用中，无人机降落时由于定位精度以及停靠时的控制精度存在误差，会导致停靠位置不准确而产生偏移，由于无人机本身体型较小，耦合机构的尺寸也会较小，此时存在的偏移会导致耦合机构的耦合程度降低，进而导致无线电能传输系统工作效率降低，影响系统正常工作。为提高系统的抗偏移特性，需要对无人机无线充电系统的耦合机构进行合理的设计及优化。笔者通过结合无人机结构特性，在用线量一致的约束条件下分析对比不同耦合机构的耦合特性，设计适用于无人机的最佳耦合机构；对耦合机构参数进行以M/l为优化目标的轻量化优化；最后通过仿真和实验验证了该耦合机构优化方法的可行性。

    Abstract:

    In the practical application of wireless power transmission technology for unmanned aerial vehicles(UAVs), inaccuracies in positioning and docking control during UAV landing can lead to errors in docking position and displacement. Due to the small size of the UAV, the coupling mechanism’s size is also limited, and any offset at this time can reduce the coupling efficiency of coupling mechanism, which in turn leads to the reduction of the efficiency of the wireless power transmission system, affecting its normal operation. Therefore, to improve the system’s anti-offset characteristics, it is necessary to design and optimize the coupling mechanism of the UAV wireless charging system. This study analyzes and compares the coupling characteristics of different coupling mechanisms with considering consistent line usage and the structural characteristics of UAVs. A suitable coupling mechanism for UAVs is then designed and the parameters of the coupling mechanism are optimized for lightweight, using M/l as the optimization goal. Finally, the feasibility of optimization method for the coupling mechanism is verified by simulation and experiment.
