Abstract
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.
