| Research Abstract |
This study presents circular polar coordinates transformation of periodic fuzzy membership function. The purpose is identification of domain of periodic membership functions in consequent part of IF-THEN rules.
The transformation to circular polar coordinates simplifies domain of periodic membership function. Moreover defuzzification method is discussed. The proposed methods are applied to the simple color construct system.
