摘要:

针对现代无人机电网电压畸变参数检测的需求,设计了一种基于Labwindows/CVI的无人机专用畸变测试系统;根据实际装备的需求,设计过程中注重便携的特点和模块化设计思想,完成了系统的硬件和软件设计;为了提高设计的准确性,该系统还采用硬件滤波和数字滤波两种滤波方式进行滤波;实际应用表明,该系统能够准确测出无人机电网的畸变参数与畸变频谱,且各项测试指标均达到了设计要求,能够满足无人机电网交直流畸变测试的需要。

Abstract:

In order to satisfy the requirement of detecting the distortion parameters for the unmanned aerial vehicle(UAV), the distortion test system of unmanned aerial vehicle power system based on Labwindows/CVI is designed in this paper. According to the requirement of the practical equipment, the portable character and the modular design idea has been adopted in the design. At the same time, the technology of hardware filter and software filter is adopted. It is shown that the test system can acquire the distortion parameters and the distortion spectrum of the power system for the unmanned aerial vehicle, and the test results reach to the design requirements, and can satisfy the distortion parameters test requirement for the unmanned aerial vehicle. 
