In Sect. 6.2, the trajectory control system model and attitude dynamics model in approximate discrete time form are obtained according to Euler approximation method. The discrete-time form of SMDO is designed, and the disturbance estimation output of SMDO is used to compensate for the negative effects of wind disturbances in Sect. 6.3. Also in Sect. 6.3, a track control method based on the DTDO is presented and a discrete time adaptive attitude controller is designed according to the auxiliary system, the NN-based SMDO, the discrete-time tracking differentiator and the BC technology. In Sect. 6.4, numerical simulation results are given to show the effectiveness of discrete-time flight control scheme, followed by some concluding remarks in Sect. 6.5.
