【Abstract】 In order to effectively predict the output power of a stirling engine under operating conditions in its design phase,three prediction models are compared:BP neural networks,multivariate regression model and neural network based combinatorial model.Computer si- mulated results indicate that in the models under comparison,neural network based combinatorial model contains minimum prediction error.更多还原
