Matlab仿真在船舶航向自动控制系统中的研究与仿真

Research and simulation of Matlab simulation in ship course automatic control system

船舶的运动状态受到众多因素的影响,尤其是各种因素的叠加会对航向自动控制系统造成潜在的不稳定。而这些不良因素一般很难在设计阶段就被发现,只有通过仿真软件,对各种影响因素进行仿真验证,才能够降低航向控制系统发生故障的概率。本文主要采用Matlab软件对船舶的航向自动控制系统进行仿真与优化,并设计合适的PID控制策略,从多种角度对船舶的状态特性和运行稳态特性进行仿真,通过采用反馈校正算法,一定程度上提升了航向自动控制系统的精度。

The state of motion of the ship is affected by many factors, especially the superposition of various factors will cause potential instability to the heading automatic control system. And these bad factors are generally difficult to be found in the design phase, only through the simulation software, a variety of factors to simulate the simulation, in order to reduce the probability of heading control system failure. In this paper, the paper uses the Matlab software to simulate and optimize the ship's heading automatic control system, and design the appropriate PID control strategy. The ship's state characteristics and running steady-state characteristics are simulated from various angles. By using the feedback correction algorithm, To a certain extent, to enhance the accuracy of the heading automatic control system.
