Abstract :
A new approach to the supervision of fuzzy controllers is presented. The supervision loop is designed to overcome some of the problems that remain unsolved, such as time-varying plants, high nonlinear plants or fine tuning of the linguistic terms given by the expert in a fuzzy controller. The supervision concept is based on the continuous adjustment of the mathematical functions used for the definition of the linguistic terms which describe the actions of the rules. The amount of adjustment is the result of a weighted combination of the results using two features observed in the control system output-the rise time and the overshoot
