The attitude control of UAV in carrier landing based on ADRC

Abstract

In this paper, the problem of unmanned aerial vehicle(UAV) pitch angle control is considered. We employ a method of active disturbance rejection control(ADRC) to solve the problem. Firstly, UAV model including windy and windless condition and disturbance model are introduced. Next, ADRC-based controller is designed for UAV model. Finally, a series of numerical simulations are presented. The simulation results demonstrate that ADRC has an excellent performance in terms of estimation of states and internal and external disturbance, attitude tracking, disturbance rejection and robustness to model uncertainties.
