A Generalized Direct Approach for Designing Fuzzy Logic Controllers in Matlab/simulink Gui Environment

A straightforward approach for designing fuzzy logic based controllers in Matlab/Simulink environment is presented in this paper. The approach focuses on the fuzzy rule base construction using the time varying values of control error (e) and its change (∆e) mapped on e-∆e space. In order to show the generalized model simplicity of the proposed approach, a fuzzy logic controller (FLC) is designed in Matlab/Simulink environment. For validation, the generated FLC block is simulated to control five different systems such as a PMDC motor speed control system, a position control system, a radar tracking control system, a synchronous generator voltage control system, and loadfrequency control of a two-area power system. The simulation results obtained by FLC are also compared with the results obtained using PID controllers for applicability validation of the developed FLC block in Matlab/Simulink environment.
