摘要

In this paper, we present a new defuzzification method for a Mamdani fuzzy controller. The method selects an element of the core of the fuzzy output set as defuzzification value, in a way that the continuity of the controller can be preserved. However, in order for this continuity to be guaranteed, some constraints on the components of the controller have to be Taken into account. Except for some constraints of continuity, convexity and points of intersection for the input and output Linguistic terms, we will define the property of linguistic continuity that has to be fulfilled by the controller. Further we Show that the new defuzzification method is computationally very efficient and we point out how the fuzzy controller can be Tuned by modifying the output linguistic terms. Finally, we also give two variants of the proposed formula.
