DG-VSMM Tracking Algorithm for Near-space Hypersonic-vehicle
摘要
Abstract
The traditional tracking algorithms can not track near-space hypersonic-vehicle(NSHV)effectively.Aiming at this problem,one kind of variable-structure multiple-model tracking algorithm(DG-VSMM)based on the directed graph was proposed.The problem that the model set of traditional variable structure multiple-model algorithm(VSMM)can not quickly jump was analyzed,and the acceleration and angular velocity were selected as the model parameters,and the directed graph of model was built.According to the target maneuver situation,the model subset having a hand in the calculation was chosen,and the local model subset was adjusted for real-time based on the posterior probability of model to realize variable-structure multiple-model tracking.The Monte-Carlo simulation results show that this method can realize the quick jump among model subsets,and the tracking precision,stability and computation are improved,and it can be applied in near-space hypersonic-vehicle tracking.关键词
