摘要: 针对临近空间高超声速滑翔飞行器机动性强、单跟踪模型稳定匹配困难等问题,在分析目标受力情况与机动特性基础上,充分考虑运动学建模适应性强和动力学建模匹配程度高的特点,提出一种运动学模型与动力学模型相结合的自适应多通道交互式多模型跟踪算法。该算法以运动学模型和动力学模型为模型集,利用似然函数值对转移概率矩阵进行实时调整,增强匹配模型在滤波中的比重,利用残差边缘分布描述滤波模型在x轴、y轴和z轴3个不同维度与目标运动的匹配程度,实现了似然函数和模型概率的一一对应。仿真实验结果表明,新算法在跟踪典型控制律下的高超声速滑翔飞行器时具有良好的适应性,在目标发生机动时误差起伏较小、稳定跟踪精度高。

Abstract: The near-space hypersonic glide vehicle (HGV) has the high maneuverability,which makes it difficult to track stably by using the single tracking model. To solve this problem,a tracking method based on adaptive multi-channel interacting multiple model is proposed. Based on the analysis of the force and maneuvering characteristics of HGV,the characteristics of strong adaptability of kinematic model and the high matching degree of dynamic model are fully considered in the proposed method. The kinematic model and the dynamic model are taken as a model set. The likelihood function value is used to adjust the transition probability matrix in real-time to enhance the proportion of the matching model. The residual edge distribution is used to describe the matching degree of the filtering model with the target motion in three different dimensions of x,y and z axes. Simulation experiments show that the proposed method has good adaptability in tracking HGV under typical control laws. When the HGV maneuvers,the proposed method has higher accuracy and stability.
