基于模糊控制的船舶全回转推进装置控制仿真

摘要

Marine azimuth thruster system includes 2 controlled variables which are azimuth and speed.As the requirements of the control system is composed of well robust,high accuracy and fast response,the control system needs more sophisticated.Considering the character of control of azimuth thrusters,this paper introduces fuzzy control technology to solve the weakness of classical PID control without model building.The paper simulates the azimuth thruster of Tai'an kou ship,and proves the advantage of fuzzy control technology,and it introduces another way to ship maneuvering.%船舶全回转推进系统是具有角度控制和速度控制的双变量控制系统,因其要求系统稳定度好,控制精度高,响应速度快,控制难度较大.本文针对其控制特点,提出在无需建模的基础上,采用模糊控制技术解决传统PID控制的局限,并通过仿真“泰安口”轮的全回转推进装置的动态响应,从理论上证明了模糊控制的优越性,为船舶全回转操控提供了另一种思路.
