? ?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(簡稱伺服電機)：用于高效和復雜型面加工的數(shù)控機床，伺服系統(tǒng)將經(jīng)常處于頻繁的啟動和制動過程中。要求電機的輸出力矩與轉動慣量的比值大，以產生足夠大的加速或制動力矩。要求伺服電機在低速時有足夠大的輸出力矩且運轉平穩(wěn)，以便在與機械運動部分連接中盡量減少中間環(huán)節(jié)。(4)寬調速范圍的速度調節(jié)系統(tǒng)，即速度伺服系統(tǒng)：從系統(tǒng)的控制結構看，數(shù)控機床的位置閉環(huán)系統(tǒng)可看作是位置調節(jié)為外環(huán)、速度調節(jié)為內環(huán)的雙閉環(huán)自動控制系統(tǒng)，其內部的實際工作過程是把位置控制輸入轉換成相應的速度給定信號后，再通過調速系統(tǒng)驅動伺服電機，實現(xiàn)實際位移。數(shù)控機床的主運動要求調速性能也比較高，因此要求伺服系統(tǒng)為高性能的寬調速系統(tǒng)。
