| 1. | The complex nonlinear pursuit - evasion model of two spacecraft in near - earth coplanar orbit is simplified to linear model , the circular region the radius of which is equal to capture radius is defined as target set , capture is achieved when the evader come into the target set and the game is over ; the boundary of useable part ( bup ) is determined , and the analytical form solution of the linear equations is obtained by backward integration of the state variables from the bup , the linear barrier of the pursuit - evasion model and the optimum thrust of the both sides are thus obtained
本文将近地共面轨道内运动的两飞行器非线性追逃模型简化为线性模型,以捕获半径的圆域定为目标集,确定目标集边界上的可用部分,并以此为各状态变量的起点,对时间进行倒向积分,求得线性方程组的解析解,从而确定了该追逃模型的线性界栅,以及界栅上对策双方的最优推力,即求得了满足最优策略时相对运动的轨迹和推力。 |
