Abstract :
In this paper, we study the well posedness of observer-based fault detection filters using the theory of singular perturbation. By proper scaling of the fault maps, it is shown that the ill-conditioning of the residual fault projector can be alleviated. This allows the construction of an approximate projector in terms of the projectors for the slow and fast subsystems.
