摘要/Abstract

摘要： 现代航空电源系统常用变频交流技术，谐波及间谐波的实时检测对飞机安全运行具有重要意义。设计实时检测系统，利用加窗插值快速傅里叶-递归带通滤波器算法检测谐波及间谐波，首先采用加窗插值傅里叶算法确定待测系统中的谐波及间谐波频带，再利用递归带通滤波器算法对确定的多个频带进行滤波遍历。Matlab 仿真测试结果表明，该系统具有高精度、高实时性的优点，适用于航电系统谐波及间谐波实时检测。

关键词: 插值, 递归带通滤波器, 航空电源, 谐波及间谐波实时检测

Abstract: Variable frequency technology is commonly used in aircraft power system, harmonics and inter-harmonics detection is of great significance for the safe operation of aircraft. Windowed interpolation FFT-RBF algorithm is proposed to detect harmonics and inter-harmonics, and real-time detecting system is designed. Firstly, the windowed interpolation FFT algorithm is used to detect the signal frequency bands, and then the RBF algorithm is used to measure the bands. Comparison between Matlab simulation and detecting results shows that the new algorithm is more accurate and has better real-time feature.

Key words: interpolation, RBF, aircraft power, harmonics and inter-harmonics real-time detection
