| 英文摘要 |
| Based on the property that fuzzy inference system can uniformly approximate any nonlinear multivariable continuous function arbitrarily well, a new nonlinear combination forecasting method is presented to overcome the difficulties and drawbacks in combined modeling non stationary time series by using linear combination forecasting method. Furthermore, the optimization algorithm based on a hierarchical structure of learning automata is used to identify the membership functions in the antecedent part and the real numbers in consequent part of the inference rule. Theoretical analysis and forecasting results related to numerical examples all show that the new technique has reinforcement learning properties and universalized capabilities. With respect to combined modeling and forecasting of non stationary time series in nonlinear systems, which has some uncertainties, the method has the excellent identification performance and forecasting accuracy superior to other existing linear combining forecasts for the same event. |
