Abstract

The paper summarizes the results of the research on angular motion dynamics carried out by the team of the authors and some problems of attitude control of nanosatellites (NS). The features of CubeSat NS passive motion dynamics are described. Conditions for the possible emergence of resonance modes are studied and discussed. Recommendations are given allowing the requirements for mass-inertia characteristics and initial conditions of NS motion to be formulated at the design stage, aimed at the NS stable motion with regard to the required equilibrium position for a wide range of orbital altitudes. Algorithms for reorientation and stabilization of NS motion are proposed based on the solution of the inverse problem of dynamics and selection of optimal nominal attitude control programs. The results of this work are implemented in practice and may be useful to the developers of small spacecraft.

低轨道超小型卫星动力学和姿态控制的一些特点

摘要本文总结了作者团队开展的角运动动力学研究成果以及超小型卫星（NS）姿态控制的一些问题。文中描述了立方体卫星（NS）被动运动动力学的特点。对可能出现共振模式的条件进行了研究和讨论。提出了一些建议，以便在设计阶段制定对质量惯性特征和超小型卫星运动初始条件的要求，目的是使超小型卫星在广泛的轨道高度范围内按照所需的平衡位置稳定运动。在解决动力学逆问题和选择最佳名义姿态控制程序的基础上，提出了调整和稳定 NS 运动的算法。这项工作的成果已在实践中实施，可能对小型航天器的开发人员有用。
