Abstract
A method for generating a minimal set of Analytical Redundancy Relations representing a system to which a plurality of sensors is associated for the observation of variables indicative of operating conditions and adapted to enable detection and isolation of faults. The minimal set of Analytical Redundancy Relations is derived from a complete set of Analytical Redundancy Relations in implicit form, for which an associated binary Fault Signature Matrix is specified, and comprises the relations associated to a minimal subset of rows of the original matrix, which has the same number of non-zero columns and the same number of distinct columns as the original matrix.
