Fuzzy adaptive PID controller applied to an electric heater in MATLAB/Simulink

Abstract

This document shows the methodological development of a fuzzy adaptive PID controller in simulation over a furnace, which is modeled with a first order transfer function plus dead time. Two types of membership functions are compared in this article, for self-tuning fuzzy controller driver. The performance of each controller was determined by calculating the integral of the absolute error value, in which a slight advantage for the Gaussian function was obtained with respect to the triangular function.
