Abstract :
In order to more eectively cope with the real world problems
of vagueness, imprecise and subjectivity, fuzzy event systems were proposed
recently. In this paper, we investigate the controllability and the observability
property of two systems that one of them has fuzzy variables and the other one
has fuzzy coecients and fuzzy variables (fully fuzzy system). Also, sucient
conditions for the controllability and the observability of such systems are
established. Some examples are given to substantiate the results obtained.
