Abstract EN
One of the IT2FS (interval type-2 fuzzy system) defuzzification methods uses the iterative KM algorithm.
Because of the iterative nature of KM-type reduction, it may be a computational bottleneck for the real-time applications of IT2FSs.
There are several other interval type-2 defuzzification methods suffering from lack of meaningful relationship between membership function uncertainties and changing of system output due to lack of clearly defined variables related to uncertainty in their methods.
In this paper, a new approach for IT2FS defuzzification is presented by reconfiguring interval type-2 fuzzy sets and how uncertainties are present in them.
This closed-formula method provides meaningful relation between the presence of uncertainty and its effect on system output.
This study investigates uncertainty avoidance that the output of IT2FS obtained by centroid or bisection methods in comparison with type-1 fuzzy system (T1FLS) moves to points with less uncertainty.
Uncertainty can enter into T1FSs and affect system response.
Finally, for proving the affectivity of the proposed defuzzification method and uncertainty avoidance, several investigations are done and a prototype two-input one-output IT2FS MATLAB code is enclosed.
