Fuzzy dynamic systems
The aim of this paper is to study fuzzy dynamic systems. The role of fuzzy sets in formation of a conceptual and computational platform for symbolic and numerical information processing is identified. We summarize essential properties of fuzzy partitions developed with the aid of families of fuzzy sets. The problem of modelling with fuzzy sets is addressed with respect to fuzzy partitions defined for system's variables. Interesting trade-offs between essential features of fuzzy models (such as precision and generality) induced by fuzzy partitions applied to the model are also pointed out. In this context we highlight conceptual links between fuzzy modelling and Qualitative Modelling. Main classes of fuzzy models are introduced.
