The accurate input-output universe of discourse (UOD) on which membership functions are
defined is hard to acquire, especially for nonlinear multi-input and multi-output (MIMO) …

There are two main fuzzy system methodologies for translating expert rules into a logical
formula: In Mamdani's methodology, we get a DNF formula (disjunction of conjunctions), and …

Derived from practical application in location analysis and pricing, and based on the
approach of hierarchical structure analysis of continuous functions, this paper investigates …

In this paper, based on an adaptive nonbackstepping design algorithm, we proposed a
novel variable universe of discourse fuzzy control (VUDFC) approach for a class of single …

Starting from the relation between flexible linguistic rules and flexible linguistic functions, this
chapter reveals the mathematical essence of approximate reasoning, and then presents an …

In this paper, the authors use the similarity measure of interval-valued fuzzy sets to
investigate approximate reasoning with interval-valued fuzzy sets, propose two …

In many practical applications of fuzzy logic controllers, fuzzy sets are used to describe a
vague value, a value and a kind of density information on the antecedent and consequent …

Using the concept of vague environment described by scaling functions [2] instead of the
linguistic terms of the fuzzy partition gives a simple way for fuzzy approximate reasoning. In …

Summary form only given. Two of the most exemplary capabilities of the human mind are the
capability of using perceptions in purposeful ways and the capability of approximating …
