本文介绍具有偏置动量轮的卫星姿态控制的一种新技术——数字逻辑协调控制。卫星姿态和姿态变化率的状态用8个特征量表示,对这些特征量进行简单的逻辑运算,即可准确地对卫星主动章动阻尼和进动控制进行协调控制。章动阻尼时,姿态绝对值不增大;姿态控制时,章动逐渐被阻尼掉。控制装置由触发器和“与”、“或”、“非”门组成,简单可靠。本方法不仅可用于太阳定向卫星,也可用于地球定向卫星。数字仿真结果验证了本方法的正确性。
This paper introduces a new technique of satellite attitude control with offset momentum wheel - digital logic coordinated control. The states of satellite attitude and attitude change rate are expressed by eight characteristic quantities. By carrying out simple logical operations on these characteristic quantities, the coordinated control of the active nutation and precession control of the satellite can be precisely controlled. When the nutation is damped, the absolute value of the attitude does not increase. When the attitude control is performed, the nutation is gradually damped. Control device by the trigger and “and”, “or”, “not” door composition, simple and reliable. The method can be used not only for the solar directional satellite but also for the directional satellite. The numerical simulation results verify the correctness of this method.
