摘要
针对低轨卫星大范围探测,设计了基于剪式控制力矩陀螺的姿态控制系统。按照2种垂轨摆扫姿态机动轨迹,获得姿态机动的期望姿态。使用剪式安装的控制力矩陀螺作为执行机构,给出框架角速率操纵率,避免出现奇异状况,简化了雅克比矩阵。仿真验证了姿控系统对于大范围探测任务的有效性。
Aiming at the wide swath detection task of the LEO satellite,the attitude control system based on scissored-pair control moment gyroscopes is designed.The desired angles of attitude maneuver are obtained according to two kinds of attitude maneuver trajectories.Scissored-pair control moment gyroscopes are selected as the attitude control actuator,and the gyro gimbal angles steer law is given,which avoids the singularity and simplifies the Jacobian matrix.The simulation result verifies the effectiveness of the attitude control system for a wide swath detection tasks.
