Membership function tuning system using defuzzy calculation

摘要

The present invention calculates an error between an output expected value with respect to an input of fuzzy inference and an output result of fuzzy inference using a singleton as the conclusion-membership function, calculates the distance proportional to the ratio of the degrees of contribution of each conclusion-membership functions in the defuzzy calculation for fuzzy inference, and uses the error and the distance as the basis to update tuning of the conclusion-membership function.
