Abstract: To address the aircraft attitude estimation problem, Unscented Kalman Filter (UKF) does not have the ability to overcome the disturbance. In order to obtain better estimation precision, an adaptive UKF is proposed. The algorithm can overcome the disturbance by introducing an adaptive factor to adjust the state gain matrix. The simulation results show the effectiveness of the proposed algorithm.
