基于数学模型的双桨船舶航向控制研究

Research on heading control of sculls based on mathematical model

目前在我国的港口贸易中,为了满足众多类型船舶的航行要求,需要设计一种高性能的航向控制器,来保证船舶的航向安全。一般情况下,可以采用双桨控制的方式,使得船舶在恶劣海况条件下依然拥有卓越的操控性能。本文主要通过建立数学模型,来模拟双桨船舶在水面上航向时的状态,并通过对航向控制器各项参数的优化,综合提升船舶的性能。通过仿真优化,可以发现双桨船舶的航向控制器能够始终提供稳定的动力,各项性能指标优秀。

At present,in our country's port trade,in order to meet the navigation requirements of many types of ships,it is necessary to design a high-performance heading controller to ensure the ship's heading safety.Under normal circumstances,the sculls can be used to control the way the ship in the harsh conditions of the sea conditions still have excellent handling performance.In this paper,the corresponding mathematic model is established to simulate the condition of a double-bladed vessel when it is on the water surface.Through optimizing the parameters of the heading controller,the performance of the ship is comprehensively enhanced.Through simulation and optimization,it can be found that the propulsion control system of a twin-propeller vessel can always provide stable power with excellent performance indexes.
