摘要： PURPOSE: Fault detector and detecting method for the pose control system of a spacecraft are provided to reduce the fault detection and enhance performance by minimizing the generation of a model filter. CONSTITUTION: A fault detector for the pose control system of a spacecraft comprise a first mutual interference multi-model fault detecting block(120) and a second mutual interference multi-model fault detecting block(130). The first mutual interference multi-model fault detecting block generates a plurality of upper filters. The upper filters comprise a normal model filter for a plurality of drivers and a fault model filter for each driver. The first mutual interference multi-model fault detecting block detects fault on the drivers from the upper filters using a mutual interference multi-model estimating technique.

摘要： PURPOSE: A fault detector for an RIMU(Redundant Inertial Measurement Unit) and a detecting method are provided to secure an improved fault detection performance because only signals of low frequency component from signals output from each inertial sensor are used for a modified extended PSA(Parity Space Approach). CONSTITUTION: A fault detector(100) comprises a signal processing unit(110) and a fault detection unit(120). The signal processing unit extracts low frequency component from the N numbers output of inertial sensors. The fault detection unit preforms the fault detection with respect to the inertia sensor through PSA by using the low frequency component of the inertial sensors offered by the signal processing unit.
