Abstract :
This paper deals with fault detection and isolation methods (FDI) in linear dynamic SISO systems. Two different approaches for the residuals generation are reviewed: parity space and parameters identification based approaches. After having recalled the analytical formulation of the residuals from the two methods, we perform a comparison between them. The interpretation of the result is discussed in this framework and some simulation results are finally presented
