Abstract

In this paper, it is shown that a fuzzy controller with singleton deffuzzification can be considered as the association of a regionwise constant term and of a regionwise non linear term, the latter being bounded by a linear controller. A systematic design method is presented that allows to design stable controlled systems. Stability conditions are given under the form of a set of inequalities which provides an admissible domain for the controller parameters.
