In this paper, a fuzzy application to design the self-tuning PID-type controller is presented. Then, two classes of the fuzzy logic systems, type-1 and type-2 fuzzy logic systems are studied and analyzed. A comparison of the results achieved in the MatLab/Simulink environment shows that the proposed self-tuning interval type-2 fuzzy logic PID controller (IT2FLPIDC) has a better dynamic performance of the load frequency control (LFC) than the PID and self-tuning type-1 fuzzy logic PID (T1FLPID) controllers in a two-area interconnected power system.
