Paper Abstract

This paper presents a novel eigenstructure assignment approach for sythesizing robust fault detection and isolation (FDI) systems with known inputs. After formulating the FDI problem in eigenstructure assigment, we proceed to develop a parametric characterization of all allowable eigenspaces for disturbance decoupling to achieve robust fault detection. In addition to the structured uncertainties, the robustness of the diagnostic observer to unstructured modeling errors is discussed. A numerical algorithm is further proposed to suppress the effects due to the unstructured uncertainties. The overall robustness of the diagnostic strategy is verfied through simulation studies on jet engine systems.
