Rania Loukil, Mohamed Chtourou, Tarak Damak . Synthesis of Nonlinear Observers for Actuator Fault Detection and Isolation. International Journal of Computer Applications. 43, 4 ( April 2012), 27-32. DOI=10.5120/6093-8279
Abstract
In this works, we use the approach based on observers such as the Luenberger observer and the sliding mode observer in order to introduce the diagnosis of nonlinear systems. The robustness of the proposed observers is tested through a physical example. The obtained results show that for non linear systems the performances of sliding mode observer observer is better than using a classic kind of observer. The synthesis of nonlinear observers will be used for actuator fault detection and isolation using residual generation. Finally, a comparison of observers' performances will be interesting for judging the effectiveness of this approach.
