【Abstract】 Identification of aeroengine model is investigated with Back-Propagation neural networks,when the test data of an aeroengine are taken for learning samples of the networks.The various states of the aeroengine are identified.The investigation shows that the deviation of the network outputs from flight data is very small.The precision and convergence speed of the identification is quite high.更多还原
