摘要
针对三轴稳定微小卫星,用四元数法建立了速率阻尼阶段的动力学和运动学模型。根据地磁场强度矢量投影到轨道坐标系的简便旋转关系,设计了采用主动磁控的拟比例微分控制器,同时分析了磁力矩器的磁偶极矩。速率阻尼仿真结果表明:该控制法有效可行,具有一定的应用价值。
The attitude dynamics and kinematics model during rate damping was built with quaternion for a three-axis stabilized micro-satellite in this paper.According to the simple and convenient projection of the geomagnetic field vector in the orbit reference frame,a quasi proportional plus derivative controller was designed with active magnetic control.And the magnetic dipole moment was analyzed.The simulation results of the micro-satellite rate damping showed that the control method was valid and was very useful ...
