| 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。本文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

| Abstract: | The parallel approaching method based on position signals of the line of sight (LOS) is often used in control of approaching phase of the space rendezvous and berthing. In this paper,the nonlinear sliding mode in the longitudinal control is improved by adding coupled items and damping items, including the angle of LOS. Its existence and stability are studied for the relative motion equations. Then the coupled multivariable nonlinear sliding mode of the LOS guidance is presented. The existence and stability are analyzed for both control of the angle of LOS and longitudinal control at the same time. |
