ON CONTROLLABILITY AND OBSERVABILITY OF FUZZY CONTROL SYSTEMS

Abstract

In order to more effectively 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 coefficients and fuzzy variables (fully fuzzy system). Also, sufficient conditions for the controllability and the observability of such systems are established. Some examples are given to substantiate the results obtained.
