Abstract

Power electronic converters have been considered by many researchers and their control and robustness under various operating conditions has a great importance. The proposed type-2 fuzzy controller employs expert experience to control the power electronic converters, considering to their non-linear and time variant structure. Using type-2 fuzzy controller enhances the stability and robustness of system. This paper's attempt is to compare general and interval type-2 fuzzy controllers in terms of dealing with non-linear uncertain plants. It is shown that general type-2 fuzzy controller leads to more accuracy in comparison with interval type-2 and type-1 fuzzy controllers in regulating the output voltage, as it is shown in simulation part. To compare the performance of the controlling methods, the Euclidean norm of regulating error is calculated.
