ADRC Flight Control System Design for Flying Wing UAV with High Aspect Ratio

The flying wing unmanned aerial vehicle (UAV) with high aspect ratio is taken as the research object in this study. Based on the theory of auto-disturbance-rejection control (ADRC) and combined with the characteristics of multi-rudder configuration of flying wing layout, the attitude controller of flying wing UAV is designed. The results show that the flight controller has good control performance, which can meet the performance requirements, and can effectively deal with the coupling effects between lateral, directional and longitudinal of the flying wing UAV. Compared with the conventional flight control methods, the controller designed in this paper has fewer parameters to be set, and a set of control parameters can be used in the whole flight envelope. The process is relatively simple. It provides a reference for further engineering applications.
