An novel electromagnetic compatibility predication method based on the hardware in the loop simulation for aircraft fuel quantity indication system

摘要

The electromagnetic compatibility (EMC) problem of fuel quantity indication system (FQIS) seriously affects aircraft' tasks, such as flight control, air combat, navigation and command, etc. Due to the shortage of FQIS's EMC predication and verification methods, a novel EMC predication method based on hardware in the loop simulation (HILS) is presented and used for aircraft FQIS. It's ensured that electromagnetic environment (EME) and work condition of FQIS are imitated distinctly. Combined with the proposed platform, experimental verification shows that the proposed method can predicate EMC problem of FQIS quantitatively and early, and verify EMC rectification quickly and accurately. Meanwhile, the predication method has a certain value for promotion.
