Abstract: The basic objective of a fault detection methodology as applied to dynamic systems is to provide techniques for detection and isolation of failed components. In this talk we consider the situation when the system dynamics can be modeled by linear or linear parameter varying (LPV) systems. Two basic approaches will be discussed, these will be the observer based design and the system inversion. When the reconstruction of the fault signal is needed the dynamic inversion based approach will be investigated. The observer-based approach will lead to the design of detection filters suitable for good fault isolation. Both approaches are based on the use of the theory of invariant subspaces elaborated first for LTI systems. These results will be extended for LPV systems that can be used to solve certain nonlinear filtering and control problems in automotive and aerospace applications.
