针对复合式高速直升机在不同飞行模式过渡过程中气动特性和操纵方式变化显著，并存在参数不确定的 特点，设计一种基于T-S 模糊的鲁棒跟踪控制器。根据T-S 模糊理论，将复合式高速直升机纵向非线性模型转化为 T-S 模型，在设计跟踪控制器时引入模糊前馈，采用Lyapunov 方法证明系统跟踪误差渐近稳定，并运用线性矩阵不 等式求解控制器参数。仿真结果表明：该控制器能确保复合式高速直升机准确跟踪空速参考指令，对系统的不确定 具有强鲁棒性。

Robust Controller of Compound High Speed Helicopter Based on T-S Fuzzy

In order to solve the problem of wide variation of aerodynamic and manipulation characteristics, parameter uncertainty of compound high-speed helicopter during the transition of different flight modes, a robust tracking controller based on T-S fuzzy theory is designed. According to the T-S fuzzy theory, the longitudinal non-linear compound high-speed helicopter model is transformed into the T-S model. Fuzzy feedback is introduced in tracing controller design. The Lyapunov method is used to prove that the asymptotic stability of system tracking error, and the linear matrix inequality (LMI) is used to solve the controller parameter. The simulation shows that the controller can guarantee that the compound high-speed helicopter could accurately track the airspeed reference command with strong robustness to uncertainty of system.
