拖曳声纳鱼雷的航行动力学模型等价性研究

给出了拖曳声纳鱼雷的动力学仿真与控制算法,采用计算效率较高的离散和递推的方法,算法以f1=fn=0为边界条件进行校核,当该条件满足时,就得到了系统的真实运动.加速度修正方法及搜索方向由优化方法给出,在此动力学模型的基础上,也可以获得封闭的解析式方程,只不过系统方程随n的增加会相当复杂.同时给出了基于Gauss原理的方法,并证明了它们之间的等价性.

Research of equality of dynamics model of towing sonar torpedo

This article gives the algorithm of dynamics emulation and control problems of towing sonar torpedo, and applies the effective discrete method and pass to the emulation. f _(1)= f _(n)=0 is taken as the boundary condition of the check. When such a condition is met, the real motion of the system can be gotten. The methods of modifying the acceleration and the search direction are given by optimization. On the base of this dynamics model, the enclosed analytical equation can also be gotten, but the equation of system will get very complicated when n increases. The method based on the Gauss theory is given and the equality of this method and the above mentioned one is also proved.
