潜射导弹运载器水弹道动力学系统辨识

摘要

运用基于单纯形的模拟退火算法对某潜射导弹运载器水弹道动力学系统进行了辨识，并探索了未建模不确定性及待辨识参数矢量的维数对辨识精度的影响。结果表明：未建模不确定性对辨识精度的影响较大，而待辨识参数矢量维数的影响较小；在克服未建模不确定性后，通过采用现代辨识技术可以获得系统的较完善模型。%With simulated annealing approach based on simple method, the dynamic system of some submarine-launched missile carrier′s water trajectory is identified, and the effects of no-modeling uncertainty and dimension of parameters to be identified on overall identification precision are investigated. It is shown that the former is more evident than the latter, and after no-modeling uncertainty is eliminated, a more perfect model can be acquired with modern identification method.
