摘要
随着现代船舶体积及自身重量的增加其动力系统也随之增加,而现行的船舶动力系统由于存在低频振荡﹑谐振及混沌状态等特性,整个船舶动力系统呈现非线性特性。混沌网络是近年来比较热门的研究动力系统非线性的方向之一,在船舶动力系统中得到很大发展。本文在研究现有船舶动力系统及混沌网络原理的基础上,提出基于递归的混沌网络船舶动力系统模型,通过计算系统的Lyapunov指数来评价动力系统的动力学特性,最后给出仿真结果。
With the volume and weight increasing of the ship, the power system also increasing. Because of the existence of low frequency oscillation, resonant and chaos characteristics, ship power system has the characteristics of nonlinear. This paper analyzes the principle of ship power system structure and chaotic network structure, proposed a recursive chaotic network model of ship power system, evaluate the performance of power system by calculating Lyapunov exponents.
