摘要/Abstract

摘要：

针对无人机的续航问题,文中采用在输电杆塔上安装充电平台,结合磁耦合谐振式无线电能传输技术(MCR-WPT),将发射线圈和接收线圈分别安装在充电平台和无人机上的方式来为无人机充电。使用该方法需要提高MCR-WPT系统的输出功率和传输效率。文中采用差分进化算法对双线圈MCR-WPT系统中的传输距离、谐振频率和负载电阻进行优化设计。从仿真结果可以看出,双线圈MCR-WPT系统的输出功率得到了提高,传输效率由原来的0.40提高到0.68,验证了优化方法的有效性。

关键词: 谐振式无线电能传输, 输出功率, 传输效率, 差分进化算法, 充电平台, 优化设计

Abstract: Aim

ing at the endurance of UAV, this paper adopted a method of installing a charging platform on a transmission tower and MCR-WPT to install the transmitting coil and the receiving coil on the charging platform and the UAV respectively. For UAV charging,the output power and transmission efficiency of the MCR-WPT system were required to be improved. In this paper, differential evolution algorithm was used to optimize the transmission distance, resonant frequency and load resistance of the two-coil MCR-WPT system. It could be seen that the output power of the dual coil MCR-WPT system had been improved and the transmission efficiency had increased from the original 0.40 to 0.68,which verified the effectiveness of the optimization method.

Key words: MCR-WPT, output power, transmission efficiency, differential evolution algorithm, charging platform, optimized design
