摘要
将模糊控制理论用于有大型挠性附件三轴稳定卫星的姿态控制,设计了一种常规模糊控制器。为减小常规模糊控制的稳态误差,采用模糊控制插值法和多次修正法改进模糊化处理,并运用因子动态加权,对所设计的模糊控制器进行了改进。仿真结果表明,采用改进模糊控制方案的系统响应快,稳态精度高,并保持了较强的鲁棒性,控制效果较为理想。
A basic fuzzy controller was designed for the three-axis stabilized satellite with large flexible appendages by using the theory of fuzzy control in this paper. To decrease the stability error of the basic controller, the controller was improved through the technologies such as linear interpolation, multi-modification and dynamic adjusted factor. The simulation results showed that the modified controller with the satisfied control effect had the characteristics of quick response, high stability accuracy and good robustness.
