| description | Fault detection for automotive semi-active shock absorbers is a challenge due to the non-linear
dynamics and the strong influence of the disturbances such as the road profile. First obstacle for this task,
is the modeling of the fault, which has been shown to be of multiplicative nature. Many of the most
widespread fault detection schemes consider additive faults. Two model-based fault algorithms for semiactive
shock absorber are compared: an observer-based approach and a parameter identification approach.
The performance of these schemes is validated and compared using a commercial vehicle model that was
experimentally validated. Early results shows that a parameter identification approach is more accurate,
whereas an observer-based approach is less sensible to parametric uncertainty. |
