摘要
基于直接方法对水下航行器NPS II操纵运动数学模型中所包含的水动力导数进行了灵敏度分析。根据计算得到的水动力导数的总体灵敏度度值和定义的取舍函数,对数学模型进行了简化。然后分别基于简化模型和原始模型进行了操纵运动仿真,仿真结果的对比表明简化结果是有效的,也表明使用直接方法进行水下航行器操纵水动力导数的灵敏度分析是可行的。
Sensitivities of hydrodynamic derivatives in the mathematical model for maneuvering the underwater vehicle NPS II are analyzed with direct method. The mathematical model is simplified based on the total sensitivity values of the hydrodynamic derivatives and the defmed selective function. Then maneuvering simulations are carried out with the simplified model and the original model respectively. The comparison of the simulation results demonstrates the validity of the model simplification, which is feasible in analyzing sensitivities of hydrodynamic derivatives.
