Study On Ship Sailing Automatic Control System

With the rapid development of economic globalization, the shipping industry entered a stage of rapid development. However, due to oil price arise and the International Maritime Organization (IMO) for the strict limits of the ship energy saving. Wind power become the new energy what shipping industry to seek, and the sailing ship become a research hotspot in domestic and international shipping industry. But most research focusing on the sail aerodynamic performance and machine coordinate with sail. Lacking of researching on the ship sailing automatic control system. Therefore, the thesis do a research on automatic control system of ship sailing.This paper designing a simulation platform for sailing ship automatic control system and based on this platform do researches which making the sailing ship keep running under the energy saving, efficience and intelligent state. Firstly, this thesis study the control system of the system, designing the sailing parameters by analysis aerodynamic performance of the wing; Get the best operating sails mathematics model by mechanic principles of sailing ship; In order to keep ship course, applicating and designing the fuzzy PID control system. Secondly, designing and making the simulation platform for sailing ship. In the process of designing. First, analysis theory of the model,establish three-dimensional model of system and then make it. In this process, designing arid making the sail turning and lifting mechanism, sail and steering gear. At last, designing the electric circuit and software of the control system. The electric circuit designing include the controller circuit, the motor driving circuit, wind speed detecting, wind direction detecting, ship course detecting, detecting the angle of sail, rudder angle detecting and sail position limit detecting circuit, wireless communication circuit and human-computer interaction circuit. The software design primarily to establish the control model. Designing the program and subprogram of the system. By all the research works, this paper realize contronl the sail up and down, the best sail angle control intelligently, automatic steering which maintain the ship course stability.Above all, This paper attempt to the method which combine with studing the control system model, producting platform, designing the circuit module and the software control module. Explore and research on designing the automatic control system of sailing ship under laboratory conditions, Realize the intelligent control system which sailing automatic running and ship course keeping. And using wireless communication, touch and display terminal to optimize traditional communications and human-computer interaction style. Laid a good foundation for researching and applicating the automatic control system of sailing ship.
