Abstract
This paper considers a new approach to fault detection and isolation (FDI) for systems modeled as an interconnection of subsystems that are each subject to parametric faults. The paper develops i) the concept of a diagnostic model that parameterizes all possible subsystem faults, ii) an off-line scheme for identification of the diagnostic model, iii) a parity equation that results in a residual that is a linear function of the change in the diagnostic parameters and iv) a fault isolation scheme that does not require a recursive least squares type identifier.
