dc.description.abstractThe aim of this paper is to improve state estimation and FDI performance. We proposed an
algorithm using a model based multi-hypothesis filter (MHF). With this method, we can detect and
identify the fault on a satellite actuator. Also, we can improve the attitude estimation performance of a
satellite attitude control system. In this method, there are several models for a possible failure situation
and the model probabilities are decided from the residuals of each filter. The master filter finds the
most suitable state estimation result from the weighting sum of each filter based on probabilities. And a
probability crossing detection algorithm and thresholding algorithm based on probabilities are introduced
for fault detection and identification of satellite actuators. The simulation results demonstrate the
advantages of the MHF-based method proposed.
