伺服系統(tǒng)（servo mechanism）是使物體的位置、方位、

狀態(tài)等輸出被控量能夠跟隨輸入目標(biāo)（或給定值）的任意變化的自動控制系統(tǒng)。伺服主要靠脈沖來定位，基本上可以這樣理解，伺服電機接收到1個脈沖，就會旋轉(zhuǎn)1個脈沖對應(yīng)的角度，從而實現(xiàn)位移，因為，伺服電機本身具備發(fā)出脈沖的功能，所以伺服電機每旋轉(zhuǎn)一個角度，都會發(fā)出對應(yīng)數(shù)量的脈沖，這樣，和伺服電機接受的脈沖形成了呼應(yīng)，或者叫閉環(huán)，如此一來，系統(tǒng)就會知道發(fā)了多少脈沖給伺服電機，同時又收了多少脈沖回來，這樣，就能夠很精確的控制電機的轉(zhuǎn)動，從而實現(xiàn)精確的定位，可以達(dá)到0.001mm。直流伺服電機分為有刷和無刷電機。有刷電機成本低，結(jié)構(gòu)簡單，啟動轉(zhuǎn)矩大，調(diào)速范圍寬，控制容易，需要維護(hù)，但維護(hù)不方便（換碳刷），產(chǎn)生電磁干擾，對環(huán)境有要求。因此它可以用于對成本敏感的普通工業(yè)和民用場合。
