| 摘 要： | 航天器系统在忽略外力矩作用时,系统对总质心的角动量矩守恒使其成为非完整系统.利用这一特性讨论了带空间机械臂的刚体航天器三维姿态运动的控制问题.栽体姿态引入Calay参数,导出带空间机械臂的刚体航天器姿态运动的数学模型,利用遗传算法进行优化控制计算.通过数值仿真,表明该方法对航天器姿态控制是有效的.

| Abstract: | Due to total angular momentum conservation of the system centre of mass, the spacecraft system becomes a nonholonomic one without considering the external forces moment acting on the system. In terms of this characteristic, the three-dimensional attitude control problem of the rigid spacecraft with three manipulators is discussed in the paper. The carrier's attitude defined by Calay parameters, the mathematical model of attitude control of rigid spacecraft with space manipulators is built.Then the optimal solutions are obtained by one kind of optimal algorithm-the genetic algorithm. The results of numerical simulation show that this approach is effective for the control problem of spacecraft attitude. |
