Aircraft stability and control model using wavelet transforms

Abstract

In contrast to the conventional aerodynamic and high-order Taylor series models, the model of wavelet transform is defined. This model is a black box model and has a better efficiency in comparison to the conventional models. The wavelet model can be used as a function of high-order aerodynamic derivatives to estimate the aerodynamic behaviour of an aircraft. Different wavelet aerodynamic model structures are made and evaluated. The results show that these non-parametric models are efficient models, and in comparison to high-order Taylor aerodynamic derivatives, the number of terms and the complexity of the model are reduced.
