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
本文將近地共面軌道內運動的兩飛行器非線性追逃模型簡化為線性模型，以捕獲半徑的圓域定為目標集，確定目標集邊界上的可用部分，並以此為各狀態變量的起點，對時間進行倒向積分，求得線性方程組的解析解，從而確定了該追逃模型的線性界柵，以及界柵上對策雙方的最優推力，即求得了滿足最優策略時相對運動的軌跡和推力。 -
According to an analysis of the current various optimum methods, a new mixed type of genetic algorithm are proposed, which overcomes some typical limitations such as the decrease of hunting efficiency lack of hunting competence near the optimal solution. with a model for optimum design setup, the system brwcad are worked out with the advanced language visual basic6. 0 and the object - oriented technique
此外，針對衡重式擋土墻常規設計存在的弊病，指出其優化設計的必要性與重要性，並在比較分析已有優化方法優缺點的基礎上，引入並提出了一種新型混合遺傳演算法進行優化設計，解決了臨近最優解搜索效率降低、搜索能力不足等缺陷。
