【摘要】 在假设了无质量的系绳和地球中心引力场后 ,绳系卫星系统在同一轨道平面内运动由子星—母星之间相对位置向量描述 ,亦即由该向量的长度 (两星间距 )变化和方位角的变化而决定。在引入距离速率控制算法之后 ,系统的动力学主要由方位角运动而定。当母星轨道为圆形时 ,系统运动状态具有极限点 ,而在椭圆轨道下则有极限环。采用了非线性动态系统的方法和技术来计算极限状态和分析它们的稳定特性以及运动的分形问题。用本文中方法对TSS 1以及其他绳系卫星系统方案作了数字模拟。更多还原

【Abstract】 This paper is devoted to the dynamics of the in planar motion of Tethered Satellite System,restricted to the assumption that the tether is massless and the Earth is a central gravitational body.The motion of the system is descibed by the relative position vector between the subsatillite and the base satellite in the system.After introducing a range rate control algorithm for the magnitude of the position vector,the system’s dynamics in the end is determined by the motion of the directional angle of the position vector.In the case of circular orbit of the base satellite,the dynamics is characterized by the limit point,and in the elliptic orbit—by the limit cycle.The methods and techniques of the nonlinear dynamic system theory are adopted to compute the possible limit states of the system and to analyse their stability and bifurcation.A computer simulation is also carried out for TSS 1 mission and a mission with the base satellite in an elliptic orbit.更多还原
