Abstract

The rapid scanning motion of the turntable brings torque disturbance to the satellite body. To counteract the interference and achieve satellite control, a composite controller is proposed. First, based on the conservation of angular momentum, an integrated attitude dynamics model of the satellite-turntable is established. This model considers the interference of the offset of the turntable's center of mass, the dynamic imbalance of the moment of inertia, and the measurement error of the sensor to the model respectively. Next, the Extended Kalman filter (EKF) is used to estimate the disturbance torque. Then, a feedforward and feedback composite controller is designed to control the attitude of the satellite body and stabilize the satellite's operation. Finally, numerical simulations show the effectiveness of the proposed approach.
