We are concerned with the problem of selecting a crisp element based on information
provided by a fuzzy set, a problem which manifests itself in the defuzzification step in fuzzy …

We look at the process of defuzzification used in fuzzy logic controllers. We provide a
parametrized formulation for this procedure based upon the use of level sets which we call …

This paper addresses the defuzzification of the fuzzy set outputs of fuzzy controllers from a
comparison or ranking perspective. This is done by emphasizing the fuzzy controller as a …

The problem of selecting a crisp element based upon a fuzzy set is investigated. It is noted
that the defuzzification problem in fuzzy logic control is a special case of this problem. The …

An important subject in fuzzy control theory is tuning of a fuzzy controller. If one wants to tune
a fuzzy controller, one can focus on the choice of rules, membership functions, number of …

SELECTION OF PARAMETERS FOR A FUZZY LOGIC CONTROLLER 1. Introduction 2. A review
ot the fuzzy logic controller Page 1 Fuzzy Sets and Systems 2 (1979) 185-199. (,~ North-Holland …

When designing a fuzzy controller, the first thing to do is to choose input and output
fuzzifications. The next step consists of building the fuzzy rules table describing the …

In this paper we present some explicit formulas of fuzzy control in the simple case of one
condition. These formulas are then used on the one hand to study the effects of some design …

A linear fuzzy proportional-integral (PI) controller with one input and one output is defined in
terms of piecewise linear membership functions for fuzzification; control rules; and …

The problem considered in this paper concerns decision-making on the basis of information
presented in a fuzzy form. It differs from the usual mathematical programming problems of …
