摘要 研究了有压电智能结构的柔性太阳能帆板振动的模糊控制。建立了帆板的动力学方程,针对振动问题的特殊性,采用周期变论域设计了变论域自适应模糊控制器,提高了模糊控制的精度和自适应性能。仿真结果表明:变论域自适应模糊控制能有效抑制柔性太阳能帆板的振动,并明显优于简单模糊控制。 The fuzzy vibration control for the flexible solar panel with piezoelectric smart structure was studied in this paper. The dynamical equations of the solar panel were derived. Based on period variable universe, a variable universe adaptive fuzzy controller was designed according to the speciality of the vibration, which improved precision and adaptive ability of fuzzy control. The simulation results showed that the variable universe adaptive fuzzy controller could suppress the vibrations of the flexible spacecraft solar panel effectively, and it was better than the simple fuzzy controller.
