The x2 Fault Detection and Diagnosis for The Combined Inertial Navigation System
This paper mainly studies the x2 faults and their diagnosis in the combined navigation system.Taking the basic error model of the system as the basis,the applicable fault monitoring technology in the federal filter structure is,to detect the hard fault in the system,construct the sliding residual fault under the fault condition,to detect the soft fault in the system,and use the soft fault detection function as the basis.It is found that the proposed algorithm is very suitable in this kind of fault detection and diagnosis.
