MODEL-FREE HYBRID FAULT DETECTION AND ISOLATION METHOD FOR INERTIAL MEASUREMENT SENSORS

摘要

The disclosed non-model of the inertial sensor complex fault diagnosis method comprising the steps of diagnosing a parity equation (parity equation) of the inertial sensor failure, calculated as based on a measurement signal for a plurality of the inertial sensor in hardware replacement, and the inertial sensor with the respective signal and a step of performing a discrete wavelet transform (discrete wavelet transform), and by performing the serial monitoring (in-line monitoring) for the converted value, fault isolation that the failure has occurred in which the inertial sensor . ; According to the present invention described above, because they do not use a mathematical model of the aircraft, it can be easily applied to a complex fault diagnosis and isolation of the low-cost aircraft, such as unmanned aerial vehicle systems. ; Fault diagnosis and isolation, an inertial sensor, a discrete wavelet transform, an extra administration.
