| 摘 要： | 研究了两航天器协同轨道机动(双主动)完成近距离交会任务的最优控制问题.在考虑航天器姿态变化、对接口位置及路径约束的情况下,构建了完整的6自由度、26状态的双主动最优交会数学模型.利用高斯伪谱法分别将燃料总消耗最少和交会时间最短两种最优问题离散为大型非线性规划问题,而后应用SNOPT软件包进行了求解.在此基础上通过大量数值计算分析总结了不同初始参数对最小燃料消耗和最短交会时间的影响规律,并与主被动交会形式进行了对比.结果表明,当两航天器质量接近时,双主动交会通常可明显减少燃料消耗,或缩短交会时间；而当质量差距较大时,双主动最优交会逐渐退化为主被动最优交会.

| Abstract: | The optimal close range rendezvous of two spacecrafts was investigated.The complete 26-state model with six degree-of-freedom for the rendezvous was developed to prevent the undesired collision of spacecraft considering the attitude change,the locations of capture interfaces,and the path constraints.The minimum quadratic control and minimum-time problems were discretized into the problem of large scale nonlinear programming by means of Gaussian pseudospectral method,which was solved by the software package ... |
