【摘要】：傳統(tǒng)錨泊定位存在精度差、自動化程度低、錨泊周期短、人力勞動強度大等缺點,而基于電液控制的四錨定位系統(tǒng)解決了傳統(tǒng)錨泊的缺點。從采礦船定位系統(tǒng)的經濟性、高效性角度出發(fā),提出基于電液比例控制的錨泊定位系統(tǒng)新方案——四錨定位。以淺海鉆探類采礦船的錨泊定位系統(tǒng)為背景,在采礦船的錨泊定位系統(tǒng)上,引入了電液控制系統(tǒng)控制錨機的收放,再配合DGPS控制系統(tǒng)對采礦船實施監(jiān)控,實現程控定位和程控移位。為滿足電液控制系統(tǒng)的位置誤差及動態(tài)響應的要求,應用液壓仿真軟件AMESim建立錨泊控制系統(tǒng)的物理模型,在Matlab/Simulink中建立控制系統(tǒng)的PID模型,通過AMESim/Simulink的聯(lián)合仿真模型,證明了基于電液控制的四錨定位系統(tǒng)既保證了探礦船定位精度的要求,又提高了定位效率。通過AMESim軟件完成了電液控制液壓錨機的系統(tǒng)搭建,借助AMESim軟件強大的機械/液壓建模與仿真能力與Matlab/Simulink強大的數值計算能力,充分利用這兩個軟件的優(yōu)勢,結合PID閉環(huán)控制。仿真的對比結果表明,電液控制的錨泊定位系統(tǒng)能滿足探礦船勘探時的定位需求,通過閉環(huán)比例控制能實現控制系統(tǒng)的穩(wěn)定性、快速性以及精確性。大大減少了人工勞動強度與定位效率,實現了錨泊定位的自動化、智能化,為進一步提升電液比例控制系統(tǒng)性能、提高控制精度奠定了一定的基礎。
[Abstract]:Traditional anchor positioning has some disadvantages such as poor precision, low automation, short mooring period, large manpower and labor intensity, etc. The four anchor positioning system based on electro-hydraulic control solves the shortcoming of traditional anchor.From the point of view of economy and high efficiency of mining ship positioning system, a new scheme of mooring positioning system based on electro-hydraulic proportional control (EHPC)-four anchors positioning system is proposed.Based on the anchor positioning system of shallow water drilling mining ship, the electro-hydraulic control system is introduced to control the retracement and release of the anchor machine, and then the DGPS control system is used to monitor the mining ship.Program-controlled positioning and program-controlled displacement are realized.In order to meet the requirements of the position error and dynamic response of the electro-hydraulic control system, the physical model of the mooring control system is established by using the hydraulic simulation software AMESim, the PID model of the control system is established in Matlab/Simulink, and the joint simulation model of AMESim/Simulink is established.It is proved that the four-anchor positioning system based on electro-hydraulic control not only ensures the positioning accuracy of the prospecting ship, but also improves the positioning efficiency.The system of electro-hydraulic control hydraulic anchor is built by AMESim software. With the help of the powerful mechanical / hydraulic modeling and simulation ability of AMESim software and the powerful numerical calculation ability of Matlab/Simulink, the advantages of these two software are fully utilized and combined with PID closed-loop control.The simulation results show that the electro-hydraulic mooring positioning system can meet the positioning requirements of prospecting ship, and the stability, rapidity and accuracy of the control system can be realized by closed-loop proportional control.It greatly reduces the labor intensity and positioning efficiency, realizes the automation and intelligence of anchor positioning, and lays a certain foundation for further improving the performance of electro-hydraulic proportional control system and improving the control precision.
