航空发动机控制系统传感器FDIA系统仿真

基于卡尔曼滤波器组,建立了航空发动机控制系统传感器故障诊断系统,实现了对单个传感器故障的检测、隔离与重构(FDIA),确保了发动机控制系统即使在传感器故障发生的情况下,依然能安全可靠地工作.同时利用Simulink建立一个通用的发动机传感器故障诊断仿真平台,在此仿真平台上,对故障的诊断进行仿真验证,并分析了测量噪声对故障诊断系统性能的影响,为发动机在线传感器故障诊断系统的实现提供理论依据. 

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.A universal 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.
