Abstract:
1. A method for obtaining a predicted value of a variable, comprising the steps of: obtaining a difference of values of the variable whose value is to be predicted and a difference of values of another variable ahead of the variable whose value is to be predicted; filtering the differences with adaptive filters; obtaining a predicted difference of values of the variable whose value is to be predicted, through an algorithm of estimation with fuzzy reasoning, including fuzzy rules determined based on an amount of a difference of values of the variable whose value is to be predicted and an amount of a difference of values of the variable ahead of the variable whose value is to be predicted; and adding the predicted difference of values of the variable whose value is to be predicted to a current value of the variable whose value is to be predicted, to obtain a predicted value of the variable whose value is to be predicted.
