Chaos Optimization-based Fuzzy Neural Network Model for Dam Safety Monitoring
Tong Jianjie · Hydropower Automation and Dam Monitoring · 2008
The difficulty in dam monitoring data analysis and monitoring and forecasting model is the determination of the complex nonlinear relationship between the effect quantity and influence quantity;the ability of traditional monitoring models to solve the non-linear problem is deficient. In this paper,on the basis of combining fuzzy neural network with chaos optimization,the fuzzy reasoning ability,various influencing factors processing ability and non-linear problem-solving ability of the fuzzy neural network and the global searching ability of chaos optimization are all made full use of,and the fuzzy neural network(FNN) model based on chaos optimization is built.The fitting and forecasting of deformation of an arch dam indicates that the fitting and forecasting data obtained by this model is in good agreement with the measured data.
