A Variable Structure IMM Algorithm for Trajectory Prediction in Air Traffic Control

本文针对空中交通管制中采用相互作用多模型算法(IMM)来进行飞行轨迹预测时,可能由于模型的选取不当而造成性能变差或计算浪费的不足,提出了一种基于图论的变结构相互作用多模型(GIMM )算法。本文给出了GIMM算法的基本思想、算法的模型和计算步骤,并用GIMM算法与固定结构IMM算法进行了仿真比较。仿真结果表明GIMM算法在空管飞行轨迹预测中是更为有效和可行的。

In this paper, considering the performance degradation or the computation increase of the Interacting Multiple Model algorithm (IMM) for trajectory prediction in air traffic control owing to improper choice of motion model, a variable structure IMM algorithm based Graph Theory (GIMM) is presented. The basic idea, the mathematic model and the calculate steps of GIMM are given. In addition, a comparison in GIMM with fixed structure IMM algorithm is done by simulating. It proves that the GIMM algorithm is more effective to the problem of trajectory prediction.
