摘　　要：探讨了重力梯度小卫星采用主动磁控技术进行速率阻尼和姿态调整的一种能量方法,给出了分区控制的条件及逻辑,分析了磁控力矩的产生过程,并结合HITSAT星给出了计算机仿真计算结果。In this paper, an active magnetic control method is applied to gravity gradient satellite to reduce the angular rate and to adjust the attitude. The conditions and criterions of divided district control are given. The process of producing the magnetic control torque is analysed. Results of computer simulation indicate that the method is effective, simple and easily realized.
