Abstract: Large space hoop-column antenna satellite, as a space structure with high aspect ratio, has a wide range of applications in satellite communication, electronic reconnaissance and space remote sensing. With the continuous increase in performance requirements for antennas, the demand for larger antenna sizes has grown significantly. However, the large flexibility and weak damping characteristics of such antennas present considerable challenges for their control design.Based on the high-precision distributed attitude control of large-scale space ring-column antenna satellites, firstly, on the basis of finite element modal decomposition, the sensor/actuator layout of the ring-column antenna satellite is optimized by using the methods of system identification and modal participation factor; Considering the coupling problems of multi-joint rotation and modal vibration, such as the fixed rotation of the solar wing and the antenna to the ground, a reduction dynamic model suitable for distributed control is established by the fixed interface mode synthesis method, and the effectiveness of the model is compared and analyzed through frequency domain response analysis. Finally, the high-precision attitude and pointing control of large space antenna satellites is realized by introducing the distributed model predictive attitude control method, and the effectiveness of the distributed model predictive attitude control method is verified by numerical simulation.
