Abstract
- In this paper, a two time-scale based controller is developed for the problem of a quadrotor in the presence of wind-gust disturbances. A backstepping control and a model based PD control method are proposed to perform position (slow model) and attitude (fast model) control of the quadrotor, respectively. The wind-gust disturbances are regard as external forces and torques acting on quadrotor, which are estimated by two Square-Root Unscented Kalman filter (SR-UKF) in the fast and slow modes. Simulated results are presented to demonstrate the good performance of the controller even under wind-gust disturbances which are assumed as a mixture of multiple unknown sinusoidal signals.
