A New Defuzzification Method for Enhance Performance of Fuzzy Logic Control System

摘要

Fuzzy logic control is the actual process of mapping from a give input to and output using fuzzy logic. For the performance of a fuzzy logic controller depends on its control rules and membership functions, this paper provide a new method (Improved Semi Linear Defuzzification) of defuzzification for enhance the performance of control system. This method is knowledge based, may improve the performance of defuzzification, and perform with minimal steady state error and a large overshot.
