Abstract :
Describes the results of a simulation study of two fault detection approaches applied to a hydraulic test rig: an eigenstructure assignment approach; and a neural network based approach. The rig has a predominant natural frequency of the order of 20 Hz and is more representative of real industrial systems due to the presence of operating point nonlinearity, measurement noise and load disturbances
