摘　　要：为了解决近空间可变翼飞行器大包络飞行以及小翼伸缩过程中受到不确定性参数和未知外部干扰的问题,第一次将灰色理论引入飞行控制领域。首先对飞行器的非线性模型不确定性参数进行分析,利用灰色GM(0,N)模型精确预测不确定性参数和外部干扰;然后根据所预测的数值,设计了基于灰色预测滑模控制的鲁棒飞行器,从而有效补偿不确定性参数和外部干扰对飞行器的影响。仿真结果表明,灰色GM(0,N)模型能够有效预测不确定性参数和未知外部干扰,并通过所设计的飞行控制器补偿其影响,保证了飞行器的稳定性和鲁棒性。This paper proposed a novel scheme that applied grey theory in the field of flight control for the first time,considering the unavoidable uncertainties and external disturbances of near-space morphing aircraft flying in complex aerospace environment. After analyzing the uncertainties existing in the nonlinear model of near-space morphing aircraft,GM（ 0,N） was drawn upon to accurately forecast the parameter uncertainties and external disturbances. In terms of the values of prediction,the robust controller based on grey prediction was designed to compensate the influences caused by uncertainties and disturbances.Simulation results indicate that GM（ 0,N） is effective to predict the uncertainties and external disturbances which can be completely compensated by the proposed robust controller to gurantee the stability and robustness of the near-space morphing aircraft.
