共线三星库仑编队动力学与自适应控制研究

摘要： 针对地球同步轨道处共线三星库仑编队队形保持的自适应控制问题进行研究,建立共线三星库仑编队在地球同步轨道的非线性相对运动动力学模型，研究仅使用库仑力作为控制力，实现共线三星库仑编队径向静态稳定的控制方案，并在库仑力建模中考虑德拜效应的影响.基于建立的非线性化动力学模型，同时考虑到外部扰动力的影响，设计三星共线库仑编队在地球同步轨道的构型保持自适应控制律，并利用Lyapnuov稳定性理论证明系统的闭环稳定性，进行数值仿真.

Adaptive Control Research of Two Craft Coulomb Formation in Track Radial

Abstract：In this paper, the adaptive control problem of the collinear three craft coulomb formation configuration keeping at geostationary orbit is investigated. The non linear relative kinetic model of the collinear three craft Coulomb formation in geosynchronous orbit is established, and the control strategy of only using the Coulomb force as the control force is studied to keep the radial static stability of the collinear three craft Coulomb formation. Based on the non linear dynamic model, considering the unmodeled disturbance force at space environment, the adaptive control law is designed. Finally, the numerical simulation is carried out.
