[0077] Example
[0078] Fitting a set of blowing data of a certain type of aircraft can sort out the following affine flight control system equations:
[0079] V · T = - 1 2 ρ V T 2 S m ( 2.4114 α 3 + 1.1495 α 2 + 0.067 α + 0.0179 ) - d sin ( γ ) + C F δ t cos ( α ) m δ t - 1 2 ρ V T 2 S m C D δ e δ e
[0080] γ · = 1 2 ρ V T S m ( 2.6035 α + 0.0948 ) - g V T cos ( γ ) + C F δ t sin ( α ) m δ t + 1 2 ρ V T 2 S m C L δ e δ e
[0081] α · = q - ρ V T S m ( 2.6035 α + 0.0948 ) + g V T cos ( γ ) - C F δ t sin ( α ) m δ t - 1 2 ρ V T 2 S m ...
