Abstract :
The letter deals with a new approach to diagnosis by comparison. A new class of diagnosable systems is introduced: in these systems, units and comparators used in the diagnostic process may fail. Failure of comparators introduces a new condition of test invalidation for comparison. Characterisation theorems and fault identification similarities between different comparison models are presented.
