摘要

In order to solve the problem of low accuracy of trajectory prediction for near space vehicles, this paper, firstly, establishes the dynamic model of the near space vehicles and simplifies the model according to the equilibrium glide characteristics, so as to obtain the prediction model. Then, the parameters of the simplified equilibrium glide prediction model can be identified by the least square method combined with the previous observation data. On this basis, to further eliminate the prediction error caused by the inadequate accuracy of the prediction model, the time-varying identification parameters approach is presented instead of the original fixed parameters by the small interval constant method. Finally, the comparison simulations illustrate the efficacy and advantage against the traditional ballistic prediction.
