| 摘 要： | 建立了飞控系统的Ｔａｋａｇｉ－Ｓｕｇｅｎｏ（Ｔ－Ｓ）模糊模型；给出了设计模糊状态反馈控制器，保证闭环系统全局渐近稳定、具有一定衰减率稳定的两个充分条件；提出了采用线性矩阵不等式（ＬＭＩ）方法，将该充分条件转化为对线性矩阵不等式族寻求ＬＭＩ可行解的凸优化问题，得到了稳定性分析和模糊状态反馈控制器设计的新方法。仿真结果表明，所提出的设计方法方便有效，控制器鲁棒性好。

| Abstract: | Takagi Sugeno(T S) fuzzy model of flight control systems is established. The sufficient conditions of asymptotic stability and stability with decay rate for the closed loop systems via fuzzy state feedback controller are presented. Based on the technique of linear matrix inequality (LMI), a new approach of stability analysis and fuzzy state feedback controller design through converting the conditions to the equivalent LMI problems to find the feasible solutions for a set of linear matrix inequalities is proposed. Simulation results demonstrate that the approach is valid, and the robustness of control systems is nice. |
