| 摘 要： | 采用多模态滑模控制方法实现了交会对接末段复杂的飞行轨线. 多模态滑模控制的切换函数以分段函数描述,代表多个滑动模态. 相比于传统滑模控制,多模态滑模控制耗能少. 将交会对接末段分为接近、绕飞和并拢3个相互衔接的过程,根据各不同过程的控制任务,设计了相应的多模态滑模控制器. 对系统进行了仿真,结果表明多模态滑模控制方法能够实现交会对接末段的复杂轨线,且符合精确、节能的要求.

| Abstract: | The multi-slide-mode control (MSMC) is used to realize the complex flight trajectory of the terminal phase of rendezvous and docking (R&D). The switching-function of MSMC is described by piecewise function, which represents multiple sliding modes. The MSMC is more energy-saving than conventional sliding mode control. The terminal phase of R&D is divided into three connected phases, approaching phase, flying-around phase and closing phase. According to the control task of the above phases, the MSMC is designed respectively. The control system is simulated and the results show that the MSMC can accomplish the complex flight trajectory and the procedure is high-precision and energy-saving. |
