径向两星库仑编队队形保持自适应控制研究

研究地球同步轨道处径向两星库仑编队队形保持的自适应控制问题.建立了双星库仑编队在地球同步轨道处径向两星库仑编队动力学模型.基于建立的非线性化动力学模型，同时考虑到外部扰动和动力学模型误差等因素，设计径向两星库仑编队在地球同步轨道处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.最后进行数值仿真，并与传统PID控制进行了比较.仿真结果表明提出的自适应控制律响应速度快，稳定性好，编队构型能够收敛到期望值，控制性能明显优于PID控制.

Adaptive Control of Two Craft Coulomb Formation in Track Radial

The adaptive control problem of two craft Coulomb formation configuration keeping at geostationary orbit is investigated. the non linear relative kinetic model of the two craft Coulomb formation at geostationary orbit is established. Based on the non linear dynamic model, considering the unmodeled disturbance force in space environment and the model error generated during the non linear dynamic model, an adaptive control law is designed. The numerical simulation is carried out, and the results are compared with the traditional PID control. The simulation results show that the proposed adaptive control law has fast response, good stability, and the formation configuration can converge to the expected one. The control performance is also proved to be better than PID control.
