| 摘要: |
| 针对失控翻滚目标任意位置悬停的控制问题进行研究。在目标器轨道坐标系下建立任意偏心率的三维相对运动方程，并分析失控翻滚目标的姿态运动特性。将悬停问题解耦为三个通道的二维模糊控制问题，并以x通道为例进行Mamdani型模糊控制器设计。确定相应的模糊子集、隶属度函数以及模糊控制规则表，采用面积中心法解模糊化。通过数值仿真验证了模糊控制器的控制性能。 |

| Abstract: |
| The problem of any selected position hovering control of uncontrolled tumbling satellite was researched. A three-dimensional relative motion equation of arbitrary eccentricity was established in the target orbital coordinate system, and the attitude motion characteristics of the uncontrolled tumbling satellite were analyzed. The hovering problem was decoupled into two-dimensional fuzzy control problem of three channels, and the Mamdani fuzzy controller was designed with the channel x as an example. Determining the corresponding fuzzy subset, membership function and fuzzy control rule table, the fuzzy was solved by using the area center method. The control performance of the designed fuzzy controller was verified by numerical simulations. |
