Research On The Four Anchor Position And Control System Of Large Scale Exploration Ship

Traditional mooring positioning has the disadvantages of poor accuracy, low degree of automation, mooring cycle short, labor strength is large, and four anchor positioning system based on electro-hydraulic control solves the shortcomings of traditional mooring. Starting from the mining ship positioning system of economic and efficiency point of view, based on electro hydraulic proportional control mooring positioning system in the new scheme, four anchor is introduced. In shallow water drilling of the mining ship mooring positioning system as the background, in the mining ship mooring positioning system, the first of more introduced electro-hydraulic control system control the retraction of the windlass, coupled with the DGPS navigation control system for monitoring the implementation of the mining ship, achieve program-controlled positioning and programmable shift. To meet the electro-hydraulic control system of position error and dynamic response of the requirements, by applying the hydraulic simulation software AMESim an anchored physical model of the control system, establish in Matlab / Simulink control system PID model, through the AMESim / Simulink co simulation model that based on electro-hydraulic control four anchoring system ensures that the exploration ship positioning accuracy requirements, but also improves the location efficiency.Through the AMESim software, the system is built, with the help of AMESim software powerful mechanical / hydraulic modeling and simulation ability and Matlab/Simulink powerful numerical calculation ability, give full play to their respective advantages, design the PID closed-loop control system. Comparison of the simulation results show that the electro-hydraulic control of the mooring positioning system can meet the exploration prospecting ship positioning requirement, through proportional closed loop control to achieve the control system stability, rapidity and accuracy. Greatly reduce the labor intensity and location efficiency, automation and intelligence of the mooring positioning are realized, to further enhance the electro-hydraulic proportional control system performance, improve the control precision of lay the foundation for a little.
