低噪声工况下潜艇自动舵控制策略研究

摘要

为了降低操舵系统的辐射噪声,利用遗传算法及粒子群法,以降低舵机噪声及提高控制精度为目标,开展自动舵控制策略的优化研究,并利用潜艇运动实时仿真系统和舵机液压系统组成的半实物联合仿真系统,开展相关半实物仿真试验.试验结果表明,该低噪声自动舵控制策略能有效规划舵板的打舵速度及舵角,既能满足潜艇的操纵性需要,又能降低操舵辐射噪声.%This paper includes two main parts, the first part is study of autoadaptation for low noise autopilot, the second part is semi-physical simulation test. The test indicate; the autopilot control system can depress noise and keep the control precision; adapt the changes of ocean wave.
