The Anti-interference Maneuver Control Based on Extended Observer for Quadrotor UAV

In this paper, a new anti-interference three-loop control strategy is proposed for the maneuver control of the quadrotor. This strategy consists of an extended state observer (ESO) and a three-loop controller. Considering the maneuver ability is the premise of the wide use of the quadrotor, the novel three loop control method can make the system more stable and decrease the response time and over adjustment. Then the ESO is introduced to compensate the external disturbances of the quadrotor during flight. The simulation results are given to demonstrate the effectiveness of the proposed control strategy for the quadrotor during the trajectory maneuver flying.
