Using velocities predicted by this wind model, generalized
forces are calculated by multiplying wind velocities by
related aerodynamic drag coefficients. These generalized
forces are integrated into the dynamic model given in Eq.
(2) as external disturbances D(ζ ,ξ ). After incorporating the
external disturbances, the final form of the dynamic model of
the quadrotor vehicle given in Eq. (20) becomes as follows
