The obejective is to find necessary and sufficient conditions to distinguish these modes using the input/output collected online. In the case where faulty operation modes are considered the distinguishability is comparable to the fault diagnosability. As in [1] we define in this paper two notions of distinguishability : the distinguishability through the input-output of the system and the distinguishability through the parity’s residues of each mode. The necessary and sufficient condition (NSC) of distinguishability through resudial parity in [1] was obtained in the case where the order of space parity modes are identical. In this article we lift this assumption. We show in this context two main results : NSC of distinguishability through resudial parity wich generalize the NSC of [1] and we proove the equivalence between the two notions of distinguishability. In addition to these results, we show a necessary condition (NC) of distinguishability. It covers about the order of the parity space of the modes.Show less >
