07 - Systems, Subsystems and EquipmentFAULT DIAGNOSIS METHOD STUDY FOR COMPLEX SYSTEM BASED ON KALMAN FILTERSW. Niuš, J. Cheng, Xian Institute of Applied Optics, China; W. Niuš; šAVIC Computing Technique Research Institute, China A challenge in the fault diagnosis applications of complex system is the design of a scheme which can distinguish between model uncertainties, disturbances and the occurrence of faults. A variable threshold algorithm is proposed which generate upper-and-lower bound trajectories. The algorithm takes the parametric uncertainties into consideration which can distinguish an fault from uncertainties. |
