摘要
空间交会停靠段的控制经常采用的一种方法是基于视线位置信息的平行接近法.对纵向控制中的非线性滑动模态控制方法进行了研究和改进,考虑了视线角对纵向控制的耦合作用,增加了耦合项,并进行了存在性和稳定性分析.对于横向和纵向同时协调控制,提出一种多变量互相耦合的非线性滑动模态视线制导控制方法,并对同时协调控制进行了存在性和稳定性分析.
The control of approaching phase of the space rendezvous and berthing often uses the parallel approaching method based on the signal of the line of sight (LOS) position. The nonlinear sliding modal in the longitudinal control is improved by adding the coupled item and the damping item including the LOS angle. Its existence and stability are proved for the relative equations. The coupled muhivariable nonlinear sliding modal of the LOS guidance is presented. The existence and stability are proved for the coordinated control
