In this paper, the fuel electronic control system of the engine as an engine control process is designed and constructed to provide the fuel adjustment function of the aero-engine. Then, the electromagnetic pulse (EMP) experiment is established by exposing it to electromagnetic field pulses of thebounded-wave simulator. Now, the damage threshold is also determined. At the same time, the induced differential voltage and common current signals are measured through the printed circuit board (PCB) port, which is necessary to cause a specific microprocessor to fail. The wavelet transform is employed to establish a time-frequency method to process the induced voltage signal. The susceptible frequency areas and coupling energy distribution are applied to the speed acquisition system. Their characteristics are employed to propose a new electromagnetic interference decrease method in both time and frequency domain. This method could be considered as a useful tool for studying the electromagnetic pulse coupling interference.

电磁脉冲对发动机燃油电子控制系统影响的实验分析

在本文中,作为发动机控制过程的发动机燃油电子控制系统被设计和构造为提供航空发动机的燃油调节功能。然后,通过将其暴露在有界波模拟器的电磁场脉冲中来建立电磁脉冲(EMP)实验。现在,还确定了损坏阈值。同时,通过印刷电路板(PCB)端口测量感应的差分电压和公共电流信号,这对于引起特定的微处理器故障是必需的。利用小波变换建立时频方法来处理感应电压信号。敏感的频率区域和耦合能量分布应用于速度采集系统。利用它们的特性,提出了一种在时域和频域上都减小电磁干扰的新方法。该方法可以被认为是研究电磁脉冲耦合干扰的有用工具。
