Study on the Technique and Error Analysis of Nonlinear Combining Forecasts Based Fuzzy System

A combination forecasting method based on fuzzy logical system is presented in this paper. The main idea of this method is that the nonlinear combination forecasting function Φ(x) can be simulated by Takgi Sugeon fuzzy model. Not only the difficulty of constructing Φ(x) is reduced, but also the predicted precise is improved by the new combination forecasting method.
