英文摘要	Conference Name:2012 3rd Annual IEEE Prognostics and System Health Management Conference, PHM-2012. Conference Address: Beijing, China. Time:May 23, 2012 - May 25, 2012.; IEEE Reliability Society; China PHM Society; Beihang Univ., Sch. Reliab. Syst. Eng.; Univ. Maryland, CALCE Electron. Prod. Syst. Cent.; This paper deals with fault detection and isolation (FDI) in nonlinear systems using unobservability codistribution. A solution to the problem of fault detection and isolation for nonlinear systems, which is based on the relevant change of coordinate, is characterized in terms of unobservability codistribution. Then a dimensional linear state observer is constructed, according to the new system, to build a residual generation which is available to detect and isolate the occurrence of faults. The above development is illustrated through a real application dealing with the detection and isolation of two failures. 漏 2012 IEEE.
