摘要 建立了变几何进气道吸气式高超声速飞行器(AHV-VGI)的纵向模型。针对纵向模型中由于参数拟合以及可移动唇罩引入的不确定性、飞行器所受不确定外来干扰,提出了一种基于模糊干扰观测器的AHV-VGI动态面控制方案。仿真结果表明:所提方法能够对AHV-VGI系统进行有效控制,相对于传统的定几何进气道(FGI) AHV(AHV-FGI)的控制,性能更优。 Longitudinal model for airbreathing hypersonic vehicle with variable geometry inlet( AHV-VGI) is established. Aiming at problem that longitudinal model has some features such as uncertainties introduced by parameters fitting and translating cowl,and unknown external disturbance,a dynamic surface control( DSC) scheme for AHV-VGI based on fuzzy disturbance observer( FDO) is proposed. Simulation results demonstrate that the scheme can effectively control AHV-VGI system,and illustrate the control performance of AHV-VGI system is better than fixed geometry inlet airbreathing hypersonic vehicle( AHV-FGI) system.
