Fault Magnitude Estimation Based on an Extended Residual Generator

This work extends the Fault Detection and Isolation approach proposed by M.-A. Massoumnia. This extension includes a novel stage for estimating the fault magnitude which redefines the residue generator by considering a term devoted to estimate such magnitude. More precisely, the new term allows to simultaneously isolate the fault and compute its magnitude. The knowledge of the fault magnitude may be used in subsequent stages to determine if the system could continue with its operation or a graceful system detention should be implemented.
