    摘要:

    为了研究空间站平均力矩平衡姿态的影响因素,建立了空间站的姿态运动模型,分析了气动力矩对空间站平均力矩平衡姿态的影响。建立了空间站的动力学与控制模型,采用典型的比例微分控制器,分别得出了两种条件下的24组平均力矩平衡姿态(Average Torque Equilibrium Attitude, ATEA),结果表明气动力矩对ATEA的影响显著。为了保持空间站ATEA,需要提供周期性的控制力矩。气动力矩引起的空间站角动量卸载和积累效应不能被忽视。

    Abstract:

    The models of attitude movement were established in order to study the influence factors of ATEA(average torque equilibrium attitude) of the space station. The influence of the air torque on the ATEA(average torque equilibrium attitude) of the space station was analyzed. The models of dynamic and control of the space station were established. A typical proportion derivative controller was used. Groups of 24 ATEA were separately obtained under two conditions. The results show that the air torque exhibits a significant influence on ATEA. In order to keep the ATEA of the space station, periodicity of control torque need to be provided. The momentum unloading and accumulating effects of the space station induced by air torque cannot be neglected.
