高空远程滑翔鱼雷控制系统设计与仿真

An Effective Design and Simulation of Control System for High Altitude Long-Range Gliding Torpedo

针对已有的滑翔鱼雷进行改进,提出一种新型的高空远程滑翔鱼雷。这种滑翔鱼雷通过加装在鱼雷腹部的助推火箭进行低空突防,以实现远距离打击敌方潜艇的目的。分析高空远程滑翔鱼雷的工作流程,分别建立了无动力滑翔段、低空突防段和反推减速段六自由度非线性运动学和动力学模型。指出三段弹道的特点,并进行弹道设计,提出控制系统的总体要求并设计各弹道相应的控制律。基于MATLAB Simulink中Air-Weapons-Torpedoes工具箱设计仿真平台,结合总体方面计算出的流体动力参数对空中全弹道进行仿真。结果显示在该控制律下,高空远程滑翔鱼雷具有明显的增程效果和一定的突防能力,实现了预先设计的弹道。

High altitude long-range gliding torpedo is a new concept of anti-submarine weapon which was put forward in recent years. A gliding torpedo was improved in Northwestern Polytechnical University that can attack submarines from a remote distance. The air trajectory model and the design of control law are quite important in the conceptual design stage. In the full paper, we explain the trajectory model of the gliding torpedo and the control law. In this abstract, we just add some pertinent remarks to listing the two topics of explanation. The first topic is trajectory models. Section 1 develops the three mathematical models of the first topic ： aerial gliding trajectory, low altitude breaking defense trajectory and the slowing down trajectory. The second topic is the control law on the gliding torpedo and it is covered in section 2. In the second topic, the characteristics of the three sections of trajectory are pointed out and the corresponding control law of each section is put forward. Initial conditions of simulation are shown in Table 2. Finally, the whole aerial trajectory was simulated with MATLAB Simulink. The simulation results are summarized in Figs. 2 through 9. The simulation results show preliminarily that the attack range of high altitude long-range gliding torpedo and the penetration ability can indeed be realized under this control law.
