Glossary

Continuous systems: systems whose behavior is described by continuous variables governed, for example, by differential equations.

Discrete event systems: systems whose behavior is represented by a set of states and transitions, generally labeled by discrete events.

Hybrid Dynamic Systems: continuous systems to which discrete commutations, i.e. commands, are associated, or discrete-event systems to which certain continuous evolutions are associated.

Parametric faults: these affect the system's continuous dynamics and manifest themselves as an abnormal change (decrease/growth) in the nominal values of the parameters describing the system's continuous dynamics.

Discrete faults: these affect the (discrete) event dynamics of the system and are represented by the occurrence of an unobservable fault...
