摘　　要：对一类具有范数有界参数不确定Takagi-Sugeno(T-S)模糊模型系统,采用状态反馈并行分配补偿结构,综合考虑变量约束和多个性能指标,研究了约束鲁棒最优保性能飞行控制律设计问题。改进输入、输出及状态约束线性矩阵不等式,提出了带约束模糊最优保性能控制定理。在一般抗干扰控制基础上引入不确定性矩阵,证明了模糊鲁棒最优抗干扰定理。综合上述结论,推导出带约束模糊最优保性能抗干扰定理。最后,建立了飞机不确定T-S模糊模型,分别设计了满足上述3个定理的飞行控制律,并进行了仿真与对比分析,结果验证了该设计方法的有效性。For a type of Takagi-Sugeno （T-S） fuzzy systems with norm-bounded parameter uncertainties, the problem of designing a guaranteed cost robust flight control law with constraints is researched allowing for the guarantee of the various performance indexes and variable constraints via the state feedback parallel-distributed compensation. A constraint fuzzy optimal guaranteed cost control theorem is proposed through modification of the input, output and state linear matrix inequality （LMI）. A fuzzy system robust disturbance resistant theo rein is also proved with the uncertainty matrix to overcome the parameter perturbation, and the constraint fuzzy optimal guaranteed perturbation immunity theorem is derived on the basis above. Finally, the aircraft T-S fuzzy model is found and the flight control laws satisfying the preceding three theorems are designed respectively. The simulation and comparison are given and the results validate its effectiveness.
