ON A DEFUZZIFICATION PROCESS OF FUZZY CONTROLLERS
Dušan J. Simjanović, Marko T. Milojkovic · Facta Universitatis Series Automatic Control and Robotics · 2024
In this paper, innovations in the field of automatic control systems with fuzzy controllers have been considered. After a short introduction on fuzzy controllers, four different ways of a defuzzification process were introduced, and verified on the simulation of nuclear reactor fuzzy controller. The default Matlab fuzzy toolbox solution is timely most demanding, while two solutions based on the defuzzification on trapezoidal fuzzy numbers have the advantage in the process of crisp numbers calculation. Also, a solution based on the determination of the line dividing the obtained polygon into two parts of equal areas is presented.
