Adaptive Observer-Based Fault Diagnosis with Application to Satellite Attitude Control Systems

In this paper, a novel adaptive approach for fault diag- nosis is proposed. In order to enhance performance of fault estimation, the proposed fault estimator is composed of pro- portional term and integral one, which enables to improve rapidity and accuracy for fault estimation. Finally, a satel- lite attitude control example is presented to illustrate the efficiency of the presented techniques for fault diagnosis.
