摘　　要：针对飞行器具有非线性、强耦合、多输入多输出(MIMO)等特点,提出BTT滑翔式飞行器的一种鲁棒解耦控制方法。首先,采用轨迹线性化方法得到飞行器的数学模型并分析了通道间耦合的影响;然后,基于模型分段解耦控制的思想,针对区间模型进行解耦补偿器的求解,并采用定量反馈理论(QFT)进行区间多模型的鲁棒控制器设计;最后对该控制方式进行了稳定性分析及仿真验证,结果表明该方法具有良好的解耦控制效果,且在有外部干扰的情况下,系统能够很快地达到稳定的效果。A robust decoupling control method for BTT vehicle is proposed. According to the characteristics of vehicle such as nonlinearity, strong coupling and MIMO, firstly, the BTT mathematical models of vehicle are obtained by mini-derivative linearization and the result of the coupling between channels is analyzed. Secondly, decoupling compensator could be gotten and piecewise robust controller is designed by QFT. Finally, the system robust stability analysis and results from the simulation are used to illustrate the proposed control scheme feasibility.
