自由飞行态主动式自旋稳定姿态控制

Active Attitude Control for a Spin Stablized Spacecraft while Flying Freely

为改善航天器在自由飞行状态下的自旋稳定姿态控制精度,在分别采用消章和消偏的基础上,提出了一种消章消偏综合控制方法,并选用带消偏约束的消章控制法,对某细长型航天器的姿态控制进行了仿真试验。理论分析和实验结果表明,该控制法的姿态角控制精度较高,所用时间较短,可满足控制精度的要求。

To improve the attitude control accuracy of spin stabilized spacecraft in free flight, an active attitude control method, which reduced nutation and deflection synthetically, was put forward on the basis of reducing nutation and deflection respectively in this paper. The simulation was done by the new method. The theory and simulation results showed that the control accuracy of attitude angle was high and control process was short which could meet the requirement of control accuracy.
