【摘要】 系统辨识是一种通过测量并分析输入与输出响应的数据,建立系统数学模型的方法。基于最小二乘准则,以收缩映射遗传算法为辨识算法,对载人潜水器水动力系数进行辨识,获得了水平面动力学系统数学模型。通过某型深海载人潜水器的运动仿真试验,有效地验证了该种建模方法的正确性。更多还原

【Abstract】 System identification is an effective method to obtain the mathematics model of a system by analyzing it′s input and output values.With contractive mapping genetic algorithm,the hydrodynamic coefficients of a manned submersible are estimated and the relevant dynamic system is identified in the horizontal plane.The validity of the method is demonstrated by the simulation test of a deep manned submersible.更多还原
