Design of electromagnetic compatibility prediction platform for aircraft fuel quantity indication system based on hardware in the loop simulation

The electromagnetic compatibility （EMC） problem of fuel quantity indication system （FQIS） seriously affects aircrafts＇ tasks, such as flight control, air combat, navigation and command, etc. Due to the shortage of FQIS＇s EMC prediction and verification methods, a novel EMC prediction method based on hardware in the loop simulation （HILS） is presented. The EMC prediction platform of aircraft FQIS is designed and established by using the technology of HILS. Combined with practical application, the experimental verification shows that the proposed platform can predict the potential EMC problems of FQIS early and quantitatively, and verify the result of EMC rectification quickly and accurately. The prediction platform has good versatility and scalability, and a certain value for promotion.
