| Summary: | The presence of external disturbances such as wind may affect the stability of a quadrotor during flight. This paper proposes a robust autonomous flight control of a feedback linearized quadrotor model with the presence of external disturbances by using the active anti-disturbance control (AADC) technique. In the inner-loop control, the feedback linearization technique is used to simplify the nonlinear and under-actuated quadrotor dynamics into the corresponding linear representation. In the outer-loop control, the AADC technique using extended state observer (ESO) and state feedback is proposed for trajectory tracking and disturbance rejection control of the quadrotor, respectively. Here, ESO estimates the external disturbances by using only the output of the system. To evaluate the effectiveness of the proposed controller, simulations of the quadrotor were carried in which the results obtained show the advantage of the proposed control algorithm for hovering and trajectory tracking of the quadrotor. |
