| 摘 要： | 研究了非合作式自主交会对接（AR＆D）的终端接近问题。文中根据视线相对运动方程，设计了一个模糊控制器来实现终端接近制导。通过选择合适的模糊输入变量，设计了三个通道独立的模糊规则库。用乘积推理机、单值模糊器和中心平均解模糊公式获得模糊控制器输出。最后，本文用精确的轨道模型进行了数值仿真，验证了该模糊控制器是可行的，该控制器满足非合作式自主交会对接终端接近的高精度、安全无碰撞的要求。

| Abstract: | This paper studied the terminal proximity guidance of autonomous rendezvous and docking(AR&D) with non-cooperative target.A fuzzy controller was designed based on the relative motion equation described in the line of sight(LOS) coordinate frame.By selecting appropriate fuzzy input variables,three fuzzy rule bases were designed independently.Product inference engine,singleton fuzzifier and center average defuzzifier were used to calculate outputs.Finally,the numerical simulation results based on a precise orbital model demonstrate that the fuzzy controller is efficient and satisfies the requirements of precise and safety in the terminal proximity stage of autonomous rendezvous and docking with non-cooperated target. |
