基于模拟退火算法的水下航行器流体动力参数辨识

Underwater Vehicle Parameter Identification Based on Simulated Annealing Approach

运用模拟退火算法和极大似然准则，对水下航行器流体动力参数进行辨识。辨识结果表明：运用模拟退火算法，可以求得水下航行器流体动力参数的极大似然估计；与常规辨识算法相比，模拟退火算法对初值的选取要求较低。

By adopting simulated annealing approach and maximum likelihood criterion, hydrodynamic parameters of underwater vehicle were identified. It is shown that maximum likelihood estimator of underwater vehicle's hydrodynamic parameters can be acquired with the method; and comparing with ordinary identification method, SAA has fewer constraints to initial value.
