【Abstract】 In this paper we build a forecast method of simplex projection operator using fold and extension character of chaoticattracting sets in phase space. The forecast method is concerned with local nonlinear and I.yapunov characteristic exponent of predicted points, avoids the problem of traditional analogue predictive functions and equations, decreases some analogue Parameters.The method is used to forecast the time series data of I.orenz and Logistic model, and the forecast results show that the methodis simple and available, reduces compute time and has stronger forecast power within time scales and precision.更多还原
