? ?伺服系統(tǒng)的主要特點(diǎn)：(1)精確的檢測(cè)裝置：以組成速度和位置閉環(huán)控制。
(2)有多種反饋比較原理與方法:根據(jù)檢測(cè)裝置實(shí)現(xiàn)信息反饋的原理不同，伺服系統(tǒng)反饋比較的方法也不相同。目前常用的有脈沖比較、相位比較和幅值比較3種。(3)高性能的伺服電動(dòng)機(jī)(簡(jiǎn)稱伺服電機(jī))：用于高效和復(fù)雜型面加工的數(shù)控機(jī)床，伺服系統(tǒng)將經(jīng)常處于頻繁的啟動(dòng)和制動(dòng)過(guò)程中。要求電機(jī)的輸出力矩與轉(zhuǎn)動(dòng)慣量的比值大，以產(chǎn)生足夠大的加速或制動(dòng)力矩。要求伺服電機(jī)在低速時(shí)有足夠大的輸出力矩且運(yùn)轉(zhuǎn)平穩(wěn)，以便在與機(jī)械運(yùn)動(dòng)部分連接中盡量減少中間環(huán)節(jié)。(4)寬調(diào)速范圍的速度調(diào)節(jié)系統(tǒng)，即速度伺服系統(tǒng)：從系統(tǒng)的控制結(jié)構(gòu)看，數(shù)控機(jī)床的位置閉環(huán)系統(tǒng)可看作是位置調(diào)節(jié)為外環(huán)、速度調(diào)節(jié)為內(nèi)環(huán)的雙閉環(huán)自動(dòng)控制系統(tǒng)，其內(nèi)部的實(shí)際工作過(guò)程是把位置控制輸入轉(zhuǎn)換成相應(yīng)的速度給定信號(hào)后，再通過(guò)調(diào)速系統(tǒng)驅(qū)動(dòng)伺服電機(jī)，實(shí)現(xiàn)實(shí)際位移。數(shù)控機(jī)床的主運(yùn)動(dòng)要求調(diào)速性能也比較高，因此要求伺服系統(tǒng)為高性能的寬調(diào)速系統(tǒng)。
