Research on attitude control technology of flexible spacecraft based on drop pressure power plant
Based on linear active disturbance rejection control theory,research on flexible spacecraft attitude control technology is carried out to solve the attitude control problem of flexible spacecraft with inflatable deploy-able structures.By real-time fitting of pressure changes in a drop pressure power plant,a pressure drop distur-bance rejection attitude control algorithm is proposed.The simulation results show that compared to traditional constant pressure attitude control algorithm,the drop pressure attitude control algorithm reduces the consumption of working fluid by about 10%and increases the attitude holding time by 11%,and the miniaturization and light-weighting of flexible spacecraft are further realized.
