摘　　要：以描述编队飞行的相对运动方程为基础,根据线性定常系统的性质,采用最优控制理论和极小值原理设计了连续小推力作用下编队构型时间最短和燃料最省两种开关控制策略。仿真结果表明,由该方法得到的控制解能够满足线性定常系统最优控制的相关约束条件,证明了方法的正确性和有效性。与传统的有限推力最优编队构型控制方法相比,该方法不需要求解复杂的两点边值问题,仅描述运动状态转移的非线性方程组即可得到最优控制策略,具有形式简单、计算量小、利于实施等优点。Based on linearzed equation of formation flying, optimal control theory and principle of the minimum, a switching control strategy with minimum time and minimum fuel for satellite formation flying is put forward. Simulation results show that the control solutions which are obtained by this method can satisfy the optimal control of linear time-invariant system related constraints, and the correctness and reli- ability of the method is verified. Compared with traditional methods for optimal satellite formation control, the optimal control solution can be obtained by solving nonlinear equations instead of two-point boundary value. This method has the advantages of simple in form, small amount of calculation and convenient im- plementation.
