Fault detection and isolation of flight based on robust observer

Safety and reliability of dynamic systems become more and more important performance indexes. Technologies of Fault Detection and Isolation (FDI), which ensure the system advantage of safety and reliability, have received increasing research interests in recent years. In this paper, a compound approach of FDI and a slight improvement on algorithm of robust observer are proposed. Using an instance of FDI on a model of F-16 flight aerodynamic system, the advantage and feasibility of the approach are testified.
