摘要:

针对高超声速飞行器高精度轨迹跟踪问题,提出一种将滚动时域估计与交互式多模型算法相结合的强机动目标轨迹跟踪算法。给出了半速度系下的高超声速飞行器滑翔段运动模型及量测模型。利用滚动时域估计方法将状态估计问题转化为有约束的优化问题,并充分考虑飞行器滑翔段物理约束。在此基础上,为应对目标不同机动模式,借助交互式多模型算法思想建立模型集对其进行近似。分别在机动模式不变和机动模式突变的情况下对算法进行了验证。结果表明,新算法采用多个模型并行估计,即时调整模型概率后进行融合输出,能够有效避免目标跟踪模型失配,可显著提高对于高超声速飞行器这类强机动目标的轨迹跟踪精度。

Abstract:

In order to achieve high-precision trajectory tracking of hypersonic vehicles, a trajectory tracking algorithm for highly maneuverable targets combining moving horizon estimation and an interactive multi-model (IMM) algorithm was proposed. Firstly, the motion model and measurement model of the glide segment of the hypersonic vehicle under the half-velocity system were given. Then, the moving horizon estimation method was used to transform the state estimation problem into a constrained optimization problem, and the physical constraints of the glide segment of the flight vehicle were fully considered. On this basis, in order to cope with the different maneuver modes of the target, a model set was established to approximate it with the help of the IMM algorithm. Finally, the algorithm was verified under unchanged and mutated maneuver modes. The results show that the new algorithm adopts parallel estimation of multiple models, and the model probability is adjusted in real time for fusion output, which can effectively avoid the mismatch of the target tracking model and significantly improve the trajectory tracking accuracy of highly maneuverable targets such as hypersonic vehicles.
