Aerodynamic Parameter Fitting Basis on Fuzzy Neural Network
Shiling Li · Acta Simulata Systematica Sinica · 2001
It is approved that fuzzy neural network can be used as an universal approximator, it can approximate any nonlinear function at arbitrary precision. This paper uses it to make a high-precise fit of aerodynamic parameters. If the formula formed by fitting is used to calculate aircraft's flight trajectory, a great deal of storage unit and machine-time are saved. Precision can be improved in this way. It is a good method which is worthy of promoting and popularizing in calculating of aircraft's flight trajectory. The validity of this method has been demonstrated by a numerical simulation.
