Semi-physical simulation of ADRC flight control system for flying wing UAV

Based on the ADRC control theory, a semi-physical simulation system for ADRC control system of flying wing UAV with high aspect ratio was established in this study. The flight control performance of attitude and altitude was verified on its typical flight profile, and the nonlinear flight control performance under typical flight conditions in full envelope was evaluated. Some boundary flight conditions and typical interference are tested and analyzed whether the UAV can fly safely. The results of the semi-physical simulation show that the ADRC flight controller has good control performance and robustness in continuous flight in the full envelope with uncertainty of aerodynamic parameters and strong wind interference.
