A fault detection method for a nonlinear system and its application to a hydraulic test RIG

Abstract A bilinear fault detection observer is proposed for a bilinear system with an unknown input. Necessary and sufficient conditions are given for the existence of the observer. Robustness of the residual to the unknown input is achieved. The method is applied to a hydraulic test rig and some simulation results are displayed.
