摘要
为了研究航天器在不利环境下的姿态控制问题 ,利用最优控制方法讨论带有 2个动量飞轮的航天器姿态控制问题。通常航天器使用 3个动量飞轮用于控制其姿态和任意定位。当其中 1个轮失效 ,在系统角动量为零的情况下 ,可以将系统的控制问题转化为无漂移系统的运动规划问题。利用最优控制方法提出求解带有2个动量飞轮航天器的姿态控制算法 ,通过数值仿真 。
In order to study attitude control of spacecraft under disadvantageous condition , the attitude problem of spacecraft controlled by two momentum flywheels is discussed.It is well known that spacecraft can be changed its attitude and fixed arbitrarily using three momentum flywheels.When one of them fails , the control problem of the system can be converted to motion planning problem of drift free system while system's angle momentum is equal to zero. An algorithm of spacecraft attitude control with two momentum flywheels is proposed using optimal control theory. The effectiveness of the approach is verified by numerical simulation.
