| 摘 要： | 针对卫星编队飞行队形保持推导了一种利用相对轨道根数为反馈量的非线性燃料次优控制算法。该控制算法基于高斯型摄动方程采用Lyapunov控制,控制增益是时变的以便控制某轨道根数时对其余的轨道根数影响最小。这种控制算法接近于燃料最优,且可以调整增益系数来适应推力大小的不同情况。仿真结果表明,该控制方法是有效的,且相比其他的控制算法能够节省更多的燃料。

| Abstract: | A near fuel-optimal control method for satellite formation keeping is developed.The orbit errors are expressed in terms of class orbit elements.Based on Gauss's variational equations of motion,the feedback control allows specific orbit elements to be controlled with minimal impact on the remaining orbit elements. Compared to optimal control solutions,the advantage of this control method is that it can operate with little computational effort and in a near fuel-optimal manner.Simulation results show that this control method is effective and can save more fuel than other methods. |
