摘　　要：阐述了定量反馈理论(QFT)的基本原理和设计方法,针对超燃冲压发动机不同工作状态时高超声速飞行器不确定性模型,应用多环QFT设计了高超声速飞行器纵向飞行控制系统;仿真结果表明,运用QFT方法设计的控制系统不仅具有良好的跟踪性能和抗干扰性能,而且能够很好地解决飞行控制系统由于模型参数具有不确定性而造成的控制系统鲁棒性设计问题,并从工程应用角度为高超飞行器纵向飞行控制系统提供了一种鲁棒控制设计方案。Basic principles and design methods of Quantitative Feedback Theory （QFT） are reviewed. Aim at the uncertain model of a hypersonic vehicle during different work conditions of seramjet, a longitudinal flight control system is designed by using multi-loop QFT technology. Simulation results show that the designed control system not only has good tracking and anti-jamming performances, but also resolves the robust design problem caused by uncertainty of model parameters effectively. It provides a robust control design method for hypersonic vehicle from engineering application view.
