摘要
运用牛顿 -拉夫逊算法、单纯形法及模拟退火算法分别对水下航行器的流体动力参数进行了仿真辨识 ;并运用模拟退火算法对水下航行器湖上试验弹道数据进行了辨识 .结果表明 :与常规辨识算法相比 ,模拟退火算法具有全局收敛性 ;
Hydrodynamic parameters of underwater vehicle were identified respectively with Newton-Raphson method, simplex method, and simulated annealing approach; and with data measured through lake test, hydrodynamic parameter identification was done by adopting SAA. It is shown that comparing with general methods, SAA has global astringency; and with the method maximum likelihood estimator of parameters can be acquired.
