模糊逻辑系统的非线性组合预测方法与系统误差分析研究

A Study of the Technique and Error Analysis of Nonlinear Combination Forecasts Based on Fuzzy Logic Systems

本文提出一种基于模糊逻辑系统的组合预测方法。其基本思想是利用模糊系统的万能逼近特性,采用模糊Takgi Sugeno模型来进行非线性组合预测函数的Ф(x)模拟。这种全新的组合预测方法不仅降低了构造非线性组合预测函数Ф(x)的难度,而且使预测精度大大提高。

A combination forecasting method based on fuzzy logical systems is presented in this paper. The main idea of this method is that the nonliner combination forecasting function φ（x） can be simulated by the Takgi Sugeno fuzzy model. Not only the difficulty of constructing φ（x） is reduced, but also the prediction precision is improved by the new combination forcasting method.
