? ?伺服系統(tǒng)的主要特點：(1)精確的檢測裝置：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)檢測裝置實現(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)高性能的伺服電動機(jī)(簡稱伺服電機(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)常處于頻繁的啟動和制動過程中。要求電機(jī)的輸出力矩與轉(zhuǎn)動慣量的比值大，以
產(chǎn)生足夠大的加速或制動力矩。要求伺服電機(jī)在低速時有足夠大的輸出力矩且運轉(zhuǎn)平穩(wěn)，以便在與機(jī)械
運動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)自動控制系統(tǒng)，其
內(nèi)部的實際工作過程是把位置控制輸入轉(zhuǎn)換成相應(yīng)的速度給定信號后，再通過調(diào)速系統(tǒng)驅(qū)動伺服電機(jī)，
實現(xiàn)實際位移。數(shù)控機(jī)床的主運動要求調(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)。
