| Abstract: | Multivariate regression analysis and parameter optimization method (conjugate gradient method and variable metric method) are employed in the fitting of aerodynamic coefficients. A comparison and analysis of the said methods is carried out in this paper. The results can be used to calculate trajectories of flight and simulate control systems. |
