FDIA simulation of aero-engine control system sensor FDIA system

Based on a bank of Kalman filters,an aircraft engine sensor fault diagnostics system was developed,thus enabling fault detection,isolation and accommodation(FDIA) of individual sensor faults and safe operation of engine control system even in the case of sensor failure.Auniversal graphical simulation platform for aircraft engine sensor fault diagnostics was designed using Simulink software.Simulations were performed on the platform to verify the feasibility of the sensor fault diagnostics system.The sensor noise impact on the performance of sensor fault diagnostics system was also analyzed,offering valuable reference for online aircraft sensor fault diagnostics.
