摘要
在考虑地球非球形引力J2项摄动时,用Lyaounov势函数法推导了连续和离散两种控制方法,以保持与控制运行于椭圆轨道的小卫星编队飞行位置。建立了相应的数学模型,并证明两种控制方法均可实现系统的稳定。理论分析和仿真结果表明,两种方法均能在规定的时间内将伴随星控制到理想位置,并在相同的轨道条件下比较了两者的燃料消耗。
The continuous and discrete control methods to keep the position of micro-satellite forming flying that flied in ellipse orbit when J2 perturbation was in consideration were derived by using Lyapunov potential function in this paper. The models were founded. It was proved that the system stabilization could be implemented from the two methods. The theory analysis and simulation results showed that the position control of companion star was realized through these two methods in a specified time. The fuel consumption of the two control methods was compared at last.
