摘　　要：海洋环境具有复杂多变的特点,舰船在海面上航行时,会受到风浪的干扰,由此会对舰船的航向保持带来一定程度的影响。为使舰船能够始终保持稳定的航行状态,并按照既定的航向前进,从而顺利抵达目的地,需要对舰船的航向进行有效的控制。舰船的航向具有非线性特征,采用常规的线性控制系统无法达到预期中的控制效果,基于此,可在充分考虑风浪干扰的前提下,依托非线性系统的构造特点,研制开发舰船航向保持自动控制器,以此来实现控制航向的目标。The marine environment has complex and changeable characteristics.When a ship sails on the sea,it will be disturbed by wind and waves,which will have a certain degree of influence on the ship’s course maintenance.In order to make the ship maintain a stable sailing state all the time,and move forward according to the established heading,so as to reach the destination smoothly,it is necessary to effectively control the heading of the ship.The course of the ship has nonlinear characteristics,and the conventional linear control system cannot achieve the expected control effect.Based on this,under the premise of fully considering the disturbance of wind and waves,relying on the structural characteristics of the nonlinear system,the course of the ship can be developed.The goal of controlling heading is achieved by maintaining the automatic controller.
