FDI based on parameter and output estimation: An integrated approach

The pap or considors a proceduro for the fault isolation in linear systems. The proposed approach is based on the estimation of a reduced number of parameters of the original system. The selection of the parameters to be estimated follows from the evaluation of structured residuals. A reduction of the required input richness in the parameter estimation approach is reached while the fault isolability is conserved. Furthermore, an efficient way to combine the parameter and observer based approaches via parametrised observers Ls introduced. The proposed procedure is shown with an example.
