摘要: 本文讨论了自旋卫星向任意目标姿态机动的动力学问题.文中导出了一组受一串脉冲控 制力矩作用的卫星姿态运动的解析表达式.这些公式描述了角动量、章动角和姿态相位角与 控制力矩、控制次数之间的变化规律,可以直接应用于卫星姿控系统和姿态确定设计. 必须指出的是:关于将卫星自旋轴控制到垂直于轨道平面或将自旋轴控制到指向太阳, 都是本文所得结果的两个特例.Abstract: The dynamical problem of a spin satellite attitude maneuver to any aim attitude is discussed in this paper. A set of analytical formulae of attitude of the spin satellite which is applied by a series of control pulses torque have been derived. These formulae described the variational rules of angular momentum, of nutation angle, and of attitude phase angle with control torque and control times. They may be directly applied to the design of the satellite attitude control system and attitude determination. It is necessary to point out that both cases in which the spin axis is to orient normal to orbit normal to orbit or coincide with the Sun direction are all the special examples of what we obtained.
