MATLAB-Based GUIs for Fuzzy Logic Controller Design and Applications to PMDC Motor and AVR Control

摘要

An attractive and instructive approach for teaching basis of fuzzy logic-based controller design steps and effects of properties of the controller to control system by using MATLAB environment is presented in this paper. All design stages are developed in MATLAB's graphical user interface (GUI). Source codes used for both controller and to define systems to be controlled are written in separated script files using MATLAB language. Maximum and minimum values of the parameters that belong to membership functions (MFs) and rule base table are determined by using step responses and error graphics of the systems. Two different examples are given to demonstrate the usefulness of the developed tool and to visualize effect of changes of fuzzy logic-based controller parameters.
