Model-Based Fault Detection and Reconstruction for Spacecraft Actuator

Abstract

A fault detection and diagnosis (FDD) system is designed for the Spacecraft Actuator. In the FDD
system two network are used. The first RBF network is used to compensate the modeling error. The second
RBF network is used for fault reconstruction. A momentum wheel model is verified through simulation. The
analysis shows that the scheme can achieve the characteristics of high precision, good time characteristics.
