選用美國(guó)MTS Temposonics III(PB/PH)非接觸式位移傳感器
原理：由詢問(wèn)信號(hào)的電流脈沖所產(chǎn)生的磁場(chǎng)（沿波導(dǎo)管運(yùn)行）與位置磁鐵產(chǎn)生的磁場(chǎng)相交產(chǎn)生一個(gè)應(yīng)變脈沖信號(hào)，然后計(jì)算這個(gè)信號(hào)被探測(cè)所需的時(shí)間周期，便能換算出準(zhǔn)確的位置。
性能及指標(biāo)：分辨率：2um；響應(yīng)速度：比其他測(cè)量方式：快4到20倍；提供網(wǎng)絡(luò)數(shù)字輸出SSI CANBUS PROFIBUS DEVICENET ；符合歐洲CE規(guī)格
3.2.3執(zhí)行部件:比例閥（包括放大板）
此環(huán)節(jié)是電氣控制信號(hào)與機(jī)械液壓系統(tǒng)連接的關(guān)鍵部分，直接影響到控制系統(tǒng)性能的發(fā)揮，所以選用德國(guó)REXROTH的VT5005帶閥芯位置反饋的自動(dòng)式比例方向控制閥，其放大電路技術(shù)數(shù)據(jù)如下：電源電壓DC24V，功率50VA，控制電壓?9V，最大輸出電流：2.2A。
3.2.4操作顯示終端
本系統(tǒng)選用三菱的GOT940觸摸操作顯示終端，其畫(huà)面可通過(guò)配套的GT-DESIGE軟件制作并通過(guò)專用通訊電纜AC30R-9SS與PC機(jī)連接進(jìn)行數(shù)據(jù)傳送及調(diào)試。安裝此顯示終端可豐富人機(jī)界面，同時(shí)監(jiān)視多個(gè)參數(shù)，對(duì)即時(shí)分析筒閥開(kāi)啟、關(guān)閉的運(yùn)行狀態(tài)提供方便。
3.3、控制策略
利用三菱PLC豐富的指令編制控制程序，對(duì)于現(xiàn)場(chǎng)調(diào)試及不斷完善、優(yōu)化控制程序具有重大意義。整個(gè)控制程序的流程框圖如圖三所示。
3.3.1具有啟閉運(yùn)動(dòng)規(guī)律的調(diào)節(jié)給定量
圓形筒閥在啟閉過(guò)程中，根據(jù)其安裝結(jié)構(gòu)及位置可知：在運(yùn)動(dòng)到全行程的中間段時(shí)，各缸允許發(fā)生的偏差最小，為了保證液壓調(diào)節(jié)系統(tǒng)的調(diào)節(jié)品質(zhì)，可將給定量降低，放慢筒閥運(yùn)行速度。在動(dòng)水關(guān)閉過(guò)程中，為了控制蝸殼水壓上升率，筒閥關(guān)閉速度可分段進(jìn)行設(shè)置。其他啟閉規(guī)律可在筒閥的運(yùn)行實(shí)踐中總結(jié)得到，通過(guò)編制具有啟閉運(yùn)動(dòng)規(guī)律的調(diào)節(jié)給定量實(shí)現(xiàn)。
