Research On Intelligent Ship Track Control Based On Fuzzy Control

The ship,as the most important tool for maritime traffic for thousands of years,has become a business card of China to face the world.In recent years,China issued the "Made in China 2025",to accelerate the development of high-tech ship,one of the key areas.The intelligent ship industry has become the development trend of the field of shipping." Intelligent ship Code" basically covers all the functions that intelligent ships should have,in which the first thing is intelligent navigation.Navigation control for military and civil ship are both closely related with the hull and crew safety,which shows the research of ship’s Intelligence track control is very important.To study the track control system,we must first make the model of the controlled object.In this paper,we will use a method of modeling robots which is used widely in recent years.This method can limit the limit of its ability to react,and express the performance of the reaction of the ship,which is very suitable for track motion control algorithm to make the simulation experiment.The interference items will also be modeled for subsequent simulations.The basic of fuzzy control is the idea of the fuzzy mathematics and the method of theoretical,combining with other methods and converting other methods into language decision rules to control,which is conducive to simulate the manual control process and methods to enhance the control system adaptability so that it has a certain level of intelligence.Then,this paper designs a set of PID control system and fuzzy self-turning PID control system according to the model and simulates,comparing and analyzing the control effect of the two systems,and improves the simulation system.Finally,we integrate the improved virtual force field method into the fuzzy control theory and apply it to the ship track control system.We will design an anti-collision algorithm based on fuzzy logic that has the ability to deal with static barriers and also avoids movement disorders.The rules of fuzzy experts are made strictly as the International Convention on Preventing Collisions at Sea.We will use a MATLAB simulation experiment to verify that the proposed method is feasible.Finally,we will try to add more external conditions to observe whether the stability and feasibility of the system can meet the actual requirements.
