中文摘要：
研究如何从空间平台上释放绳系捕捉系统与被捕捉负载相交会，给出了交会机动可行点的求解过程。计人系绳弹性，采用高斯伪谱算法计算交会机动涉及的非线性最优控制问题。结果表明，在满足相关约束的条件下，通过调节系绳张力和捕捉系统上的推进力即可实现精确的交会控制。
英文摘要：
A study is made to utilize an elastic tethered system for the rendezvous and capturing a space payload. The necessary conditions are derived for an optimal rendezvous between a non-cooperative payload and an elastic tethered system in arbitrary orbits. The minimum energy guidance law is determined by using the direct Gauss pseudo-spectral method, and the validity of solution is well demonstrated through case studies. It is shown that the rendezvous maneuver can be achieved by using only a tension control and the out-of-plane thrust force.
