【摘要】 在人造卫星的姿态控制中,广泛地采用偏置动量轮控制系统。这种系统容易产生锥运动,也叫做章动。章动可以很快地被阻尼掉。许多作者研究了主动章动控制技术。 本文探讨了利用地球磁场和卫星上的磁偶极子之间的相互作用进行主动章动控制方案。首先分析了线性控制方案,然后分析了开关性控制方案。更多还原

【Abstract】 A momentum wheel control system is widely used for the attitude control of satellite. This system tends to induce a conical motion, also called nutational motion. Then the nutational motion will be damped out rapidly. Active nutation control techniques have been discussed by many authors.This paper deals with an active nutation control scheme by using the interaction of the geomagnetic field with a magnetic dipole on the satellite. First, a linear control scheme is discussed and then a bang-bang control scheme is analysed.更多还原
