研究航天器的能量/姿控一体化控制系统(IPACS)的设计问题。针对带有4个飞轮(3正交、1斜装)的航天器的IPACS,设计了一个滑动模态姿态控制器。设计了飞轮组的控制律,保证了在储能时,飞轮的转速变化不会对航天器的姿态造成扰动,而且不影响正常的姿态控制,同时实现了姿态控制与能量存储。针对太阳帆板的功率变化特性以及飞轮电机的输入功率限制,提出了一种新的储能功率的规划方案,使飞轮在每个轨道周期内储存和释放的能量达到平衡,同时尽量利用了太阳帆板提供的功率,从而可以有效地减少太阳帆板的面积,减轻太阳帆板的质量。为了验证所设计的IPACS的有效性,给出了一个仿真实例。
To study the design of the spacecraft’s energy / attitude control integrated system (IPACS). A sliding mode attitude controller was designed for IPACS with four flywheels (3 orthogonal, 1 oblique mounted) spacecraft. The control law of the flywheel set is designed to ensure that the change of flywheel speed does not disturb the attitude of the spacecraft during the energy storage and does not affect the normal attitude control. At the same time, attitude control and energy storage are realized. Aiming at the power variation characteristics of solar panel and the input power limitation of flywheel motor, a new plan of energy storage is proposed, which balances the energy stored and released by flywheel during each orbit period, and makes full use of the sun The power provided by the windsurfing board can effectively reduce the area of the solar panel and reduce the quality of the solar panel. In order to verify the validity of the designed IPACS, a simulation example is given.
