Abstract

An approach to fault isolation of multiplicative faults in linear systems is presented. After modeling the faults as multiplicative ones, a procedure for the design of structured residuals is proposed. The design is based on a modified version of a nonlinear disturbance decoupling algorithm used for nonlinear systems. Nonlinear techniques are required because of the time variant fault distribution matrix resulting of the multiplicative fault modeling. The contributions are the study of fault isolability, the relaxing of existence condition with respect to early results and the develop of an algorithm for the fault decoupling
