passive attitude control meaning in English

被动姿态控制
无源姿态控制

Through the analysis of attitude dynamic equation , how to realize three axis passivity stabilization of the mircrosatellite by just using environmental torque is presented . three sorts conformations of three axis passivity stabilization of the mircrosatellite by using environmental torque are put forward , one is to realize the passive attitude control of microsatellite by using the aerodynamic moment and the gravity gradient , the other two by making use of the gravity gradient and the geomagnetic moment , the attitude dynamics of microsatellite of the three sorts are analysed in detail
通过对卫星姿态动力学方程分析，给出如何利用环境力矩实现微小卫星三轴姿态被动稳定，并提出三种利用环境力矩实现微小卫星三轴姿态被动稳定方案，即一种利用气动力矩和重力梯度实现微小卫星三轴姿态被动稳定方案和两种利用重力梯度和地磁力矩实现微小卫星三轴姿态被动稳定方案，对采用这三种方案的卫星的姿态运动进行详细分国防科技大学研究生院学位论文析。
