摘要:

在高超声速滑翔飞行器(hypersonic gliding vehicle,HGV)跟踪问题中,动力学模型起到了关键作用。然而,由于再入过程中目标的结构时变以及流场等不确定因素的作用,导致目标的运动模式时变且未知。基于此,提出了以扩维半弹道再入飞行器(semi-ballistic reentry vehicle,SBRV)模型估计目标的状态和气动参数。基于目标机动过程中升阻比有界以及气动参数耦合的特性,采用SBRV模型估计的爬阻比、转阻比具有较快的收敛速度,且阻力参数的估计误差也保持总体最小。进一步分析了该模型与两种典型动力学模型之间的转换关系。通过对HGV典型机动场景的仿真跟踪表明,基于SBRV模型设计的估计器跟踪误差更小,且对目标机动检测的延时更小。

Abstract:

In the study of hypersonic gliding vehicle (HGV) tracking problems, dynamic models play a crucial role. However, due to the effects of uncertainties such as the time-variant structure of the target and the flow field during the reentry process, the motion modes of the target are time-variant and unknown. Based on this, the semi-ballistic reentry vehicle (SBRV) model with state augmentation is proposed to estimate the state and aerodynamic parameters of the target. By considering the bounded characteristics of the lift-to-drag ratio and the coupling of aerodynamic parameters during the target’s maneuvering process, the SBRV model provides rapid convergence in estimating the climb-to-drag ratio and the turn-to-drag ratio, while maintaining globally minimized estimation errors in the drag parameter. The conversion relationship between this model and two typical dynamic models is further analyzed. Through the tracking simulation in the typical maneuvering scenarios of HGV, it is demonstrated that the estimator based on the SBRV model has a smaller tracking error and a smaller delay for target maneuver detection.
