Abstract

A new attitude control method for solar sails is proposed using a single-axis gimbal mechanism and three-axis reaction wheels. The gimbal angle is varied to change the geometrical relationship between the force due to solar radiation pressure (SRP) and the center of mass of the spacecraft, such that the disturbance torque is minimized during attitude maintenance for orbit control. Attitude maneuver and maintenance are performed by the reaction wheels based on the quaternion feedback control method. Even if angular momentum accumulates on the reaction wheels due to modelling error, it can also be unloaded by using the gimbal to produce suitable torque due to SRP. In this study, we analyzed the attitude motion under the reaction wheel control by linearizing the equations of motion around the equilibrium point. Further, we newly derived the propellent-free unloading method based on the analytical formulation. Finally, we constructed the integrated attitude-orbit control method, and its validity was verified in integrated attitude-orbit control simulations.

带单轴万向节机构的太阳帆综合姿态轨道控制装置

利用单轴万向节机构和三轴反作用轮，提出了一种新的太阳帆姿态控制方法。通过改变万向节角度来改变太阳辐射压力（SRP）和航天器质心之间的几何关系，从而在轨道控制的姿态维持过程中将干扰力矩降至最低。姿态机动和维持由反作用轮根据四元数反馈控制方法执行。即使由于建模误差而导致角动量在反作用力轮上积累，也可以通过使用万向节来卸载角动量，从而产生适当的 SRP 扭矩。在本研究中，我们通过对平衡点周围的运动方程进行线性化，分析了反作用力轮控制下的姿态运动。此外，我们还在分析公式的基础上新推导出了无推进剂卸载方法。最后，我们构建了综合姿态轨道控制方法，并在综合姿态轨道控制仿真中验证了该方法的有效性。
