摘要
卫星编队飞行的难点之一是在干扰力环境下控制队形。采用了一种基于线性二次调节器(LQR)的最优控制方法,对低轨道地球卫星所受的地球扁率摄动(J2力)加以模拟,并在模拟的地球低轨道J2力环境中,对几种卫星编队进行了模拟控制,从控制精度和能量消耗的角度对控制方法进行了分析,提出了卫星编队飞行中相对距离控制和绝对距离控制需要注意的问题。
One of the difficulties of satellite formation flying is to control the formation in perturbation environment. This paper uses an optimal control method based on LQR to control satellite formation flying, and makes simulation for earth oblateness perturbation (J2 force) in the low earth orbits (LEO). Control simulations for several satellite formations are made in the simulated LEO J2 force environment. Analysis is made from the viewpoint of control accuracy and energy consumption. Several problems are raised for the relative and absolute distance control in satellite formation flying.
