船舶自动舵灰色预测模型及其DSP实现技术研究

本文应用灰色系统理论对船舶自动航行的核心部件--自动舵的控制系统进行研究,针对传统控制模型的不足之处以及自动航行的最优化要求,提出了灰色预测模型并应用DSP进行硬件实现.利用灰色理论在处理不规则和非线性问题上的优势以及DSP的高速数据处理能力,更好地克服传统PID控制的缺点,同时满足了自动舵控制的大信息量和实时性需要.

A Prediction Model of Ship Autopilot Based on the Grey Theory and Its Realization with DSP

In the paper,the control system of an autopilot that is t he main part of automatic navigation is studied with the Grey Theory.A prediction model based on the Grey Theory is brought forward and its hardware system is realized with t he application of DSP so as to meet the optimization requirement of automatic na vigation.The advantages of the Grey Theory in the domain of abnormality and non -linearity and the capability of DSP in data processing at high speed can overc ome the shortcomings of the traditional PID control,meanwhile can meet the chara cters of huge amount of information and real time for controlling the autopilot.
