| Abstract: | The precise attitude control of 3-axis stable satellite with huge single flexible battery array for steady state operation was studied in this paper. The most important four environmental disturbance torques during satellite operation was analyzed in detail to present a mathematical model describing their dynamic behavior. In view of the limitation of traditional attitude control appreach, we proposed a novel high precision feedforward compensating attitude control algorithm. The flexible satellite dynamic model was derived, based on which the simulation was carried out to compare the performance of two methods. Simulation results shows that the algorithm proposed in this paper outperforms the traditional one remarkably both in respondent time and steady state precision. |
