摘　　要：将在线变动模糊划分的模糊控制应用在挠性结构卫星单轴气浮台全物理仿真实验中，实现挠性结构的大角度机动控制，获得了机动性能好、稳态精度高的结果。在模糊控制中，模糊集合的划分在控制过程中在线变动，自动确定模糊集合隶属函数的参数，需人工设置的控制器参数很少，只需调整一个控制能量分配参数，易于应用到实际控制过程中。A fuzzy controller of varying fuzzy sets is applied in the experiment of flexible structure satellite control on single axis air bearing table to realize slew maneuver of flexible structure. Results show a good maneuver performance and a high precision in steady state. In the fuzzy control system, the fuzy sets on - line varies during control process to automatically determine parameters of membership function. Few parameters of controller need to set manually. The controller is easy to use in practical control process for only one control energy assigning parameter needs to adjust.
