摘要
基于非线性动力学模型,研究了环绕编队航天器的相对运动控制问题,介绍了一种基于平均轨道根数的航天器编队飞行非线性闭环控制方法。以航天器在惯性坐标系下位置速度向量误差为输入量,给出了一种全状态反馈控制律,利用Lyapunov方法证明该闭环系统是渐进稳定的;最后利用该方法对一个编队进行控制,仿真结果表明了该控制方法的可行性。
A nonlinear control law of satellites formation flying is presented, which feeds back traditional Cartesian position and velocity tracing errors. The tracing errors are required based on mean elements. The asymptotic stability of the feedback system is proved with Lyapunov method. A numerical simulation is given to show the control effect. The conclusion shows that it call be used to maintain the satellites formation precisely.
