操作按鍵、分相電容、接線端子等組成。智能伺服放大器以專門單片微處理器為基礎(chǔ)，通過輸入回路把模擬信號(hào)、閥位電阻信號(hào)轉(zhuǎn)換成數(shù)字信號(hào)，微處理器根據(jù)采樣結(jié)果通過人工智能控制軟件后，顯示結(jié)果及輸出控制信號(hào)。</p><p style="text-indent:25px">閉環(huán)控制中閥位信息的重要性：閉環(huán)控制系統(tǒng)亦稱反饋控制系統(tǒng)，這是一種較基本的控制系統(tǒng)。在閉環(huán)控制系統(tǒng)中，被控信號(hào)以反饋方式送入調(diào)節(jié)器的輸入端，作為不斷引起控制作用的依據(jù)，而控制的目的是盡可能地減少被控量與其設(shè)定值之問的偏差。閥位測(cè)量在工業(yè)過程控制中起著非常大的作用，準(zhǔn)確、及時(shí)的測(cè)量閥門閥位，直接決定調(diào)節(jié)系統(tǒng)調(diào)節(jié)的準(zhǔn)確性、快速性、穩(wěn)定性等指標(biāo)。測(cè)量信號(hào)的可靠性和準(zhǔn)確性是決定自動(dòng)控制系統(tǒng)品質(zhì)的基礎(chǔ)。此電站中有近百臺(tái)電動(dòng)調(diào)節(jié)閥需要參與閉環(huán)控制。在閥門調(diào)試過程中，發(fā)現(xiàn)部分閥門實(shí)際開度和閥位測(cè)量開度不對(duì)應(yīng)，閥門向關(guān)閉方向偏差呈偏大趨勢(shì);實(shí)際操作閥門時(shí)，發(fā)現(xiàn)當(dāng)閥門從開向關(guān)，或者從關(guān)向開的過程中，存在一定比例的閥門行程操作但閥位顯示無變化，即閥位測(cè)量回程存在死區(qū)的現(xiàn)象廠。電動(dòng)調(diào)節(jié)閥由于不需要進(jìn)行系統(tǒng)調(diào)試，所以省去許多麻煩，節(jié)約了大量的時(shí)間，縮短竣工日期。</p><div
