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.
One of the most commonly used methods for the control of the docks in the rendezvous of space is the parallel approach based on the location information of the sight line. The nonlinear sliding mode control method in longitudinal control is studied and improved. The coupling of the viewing angle to the longitudinal control is considered , The coupling terms are added, and the existence and stability analysis are carried out.For the simultaneous horizontal and vertical coordinated control, a multivariable coupled nonlinear sliding mode gaze guidance control method is proposed and the simultaneous coordinated control exists Sexual and stability analysis.
