MECHANICAL PROPERTY PREDICTION MODEL OF STRIP BASED ON PSO-BP NEURAL NETWORK

摘要

Mechanic property prediction of hot rolled strip has enormous economic benefits and vast applied prospect.BP neural network is used almost in Mechanic property prediction of hot rolled strip in literatures.But BP has local infinitesimal defect.Combined with PSO (Particle Swarm Optimization) global optimization algorithm,a new PSO-BP neural network is established.The PSO-BP algorithm takes on advantages of global optimization ability,the rapid constringency of BP rapid training algorithm,the ability of nonlinear approach of multilayer feedforward network,and improves the performance of Neural Network.PSO-BP neural network model has good application foreground.
