中文摘要：
研究了空天飞行器（ASV）再入姿态的具有闭环极点约束的模糊保性能控制律的设计问题。基于ASV再入段存在参数摄动的不确定姿态动态系统的T—S模糊模型，考查姿态角和角速率误差的镇定问题，结合圆盘极点约束，导出了具有极点约束的模糊保性能控制律存在的条件，基于Matlab的LMI（Linear Matrix Inequalities）和FLC（Fuzzy Logic Control）工具给出了ASV再人姿态的具有闭环极点约束的模糊保性能控制器的设计方法。仿真结果验证了算法的有效性。
英文摘要：
The design problem of fuzzy guaranteed cost controller with pole placement constraints for aerospace vehicle＇s re-entry attitude control is studied. The uncertain attitude dynamic system descriptor during ASV＇s （aerospace vehicle＇ s） re-entry phase based on TS fuzzy model with parameter perturbation is considered firstly, then, the stabilization problems of attitude angles and angular velocity errors are researched, and combined with disk pole constraints, a condition for the existence of fuzzy guaranteed cost control law with pole placement constraints is derived. Finally the design techniques of fuzzy guaranteed cost controller with pole placement constraints for ASV＇s re-entry attitude control are considered, which can be solved by using LMI （linear matrix inequalities） and FLC （fuzzy logic control） tools of Matlab. The simulation results demonstrate the ef fectivity of the proposed method.
