Embodiment Construction
[0024] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:
[0025] In view of the deficiencies in the prior art, the idea of the present invention is to firstly use the similarity criterion and the Taylor expansion principle to compress the sampled data, greatly reducing the amount of sampled data and time; then use the dynamic data and steady-state data in the compressed sampled data to train respectively The dynamic airborne model based on the sparse autoencoder and the steady-state airborne model based on the BP neural network, and finally set the corresponding quasi-steady-state judgment logic, use the dynamic model of the sparse autoencoder in the dynamic process, and use the dynamic model in the steady-state process BP network steady-state model.
[0026] In order to facilitate the public's understanding, the technical solution of the present invention will be described in detail below by taking an engin...
