Deformation prediction research based on T-S fuzzy neural network

T-S fuzzy neural network model is based on the fact that the advantages and disadvantages of fuzzy system and artificial neural network have obvious complementarity,which is used in deformation prediction.Through the analysis of measured data and simulation data,comparison on advantages and disadvantages of three evaluation standards between the T-S fuzzy neural network and BP neural network, a wavelet neural network has been carried out.The three evaluation standards include prediction precision, algorithm stability and effective interval.As a result,in the deformation prediction,especially in the forecasting by using long period monitoring data,the T-S fuzzy neural network has some certain advantages.
