Longitudinal Control Method for Full-Wing UAVs Based on Vector Field and Active Disturbance Rejection Control Method

To enhance the poor longitudinal anti-disturbance ability and weak climbing ability of the full-wing UAV, a method of height trajectory tracking control law based on vector field and active disturbance rejection control method in is proposed. Firstly, analyze the longitudinal-direction stability and manoeuvrability of the UAV. Secondly, based on active disturbance-rejection control (ADRC) theory, design the pitch angle and climb rate controllers. Finally, an altitude trajectory tracker is designed based on vector field theory (VF). The simulation results show that the designed controller has good control performance, robustness and wind resistance. At the same time, the parameter setting process is relatively simple, and actual measurable physical quantities can be used to provide reference for further engineering applications.
