综合轮控高精度优点和小卫星高集成度与姿态机动的要求,以反作用轮为执行机构,采用模型状态轨迹跟踪法,在反作用轮速率饱和约束条件下,进行了模型状态轨迹和基于模型状态轨迹控制律的设计。此外,还针对飞轮摩擦等带来的常值干扰,对控制律进行了修正,以提高控制精度。仿真结果表明,此控制方法能较好地实现小卫星姿态的大角度机动。
With the advantages of high accuracy of integrated wheelset control, high integration of small satellites and attitude maneuver, the reaction wheel is taken as the executive body and the model state trajectory tracking method is used to model the state trajectory and the model state Design of trajectory control law. In addition, the control law is also amended to improve the control accuracy due to the frequent interference caused by the friction of the flywheel. Simulation results show that the proposed control method can achieve high-angle maneuver of small satellite attitude.
