摘　　要：针对卫星入轨或需要能源补给的太阳捕获情况,提出了一种基于极简系统配置的太阳捕获姿态控制方法,该方法仅采用高可靠、低功耗、低成本的磁强计和磁力矩器即可实现太阳捕获控制。文中通过对自旋卫星的姿态动力学进行分析,获得了阻尼力矩作用下卫星滚动-偏航通道的姿态运动规律,进而给出太阳捕获控制方法,并通过仿真和在轨应用说明了该方法的有效性。该方法的提出,为卫星在轨太阳捕获控制提出了一个新的思路,通过该方法可以确保卫星采用极简配置即可实现太阳捕获。An attitude control method is provided by using pure magnetic for sun acquisition or for the broken-down satellite that need to supply energy.In the method,the attitude is controlled by magnetometer and magnetic torquer that are high reliable,low power and low cost.In this paper,by attitude dynamics analysis of spin satellite,attitude motion law of roll-yaw is firstly obtained under damping torque.Then,the attitude control method is introduced,which is based on that.The simulation results and actual data on orbit indicate that the method is stability and effective.The method has the features of simple configurations that can be used to realize sun capture,which is a new think provided for engineering application in the future.
