伺服系統(tǒng)本質(zhì)上是一種隨動(dòng)系統(tǒng)。只不過(guò)被控量是位移或是其對(duì)時(shí)間的導(dǎo)數(shù)。如果要問(wèn)什么是隨動(dòng)系統(tǒng)，就是一個(gè)系統(tǒng)的輸出盡可能以快，精確的方式復(fù)現(xiàn)輸入信號(hào)。其衡量的指標(biāo)有超調(diào)量、延遲。

伺服系統(tǒng)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(dòng)控制系統(tǒng)。伺服的主要任務(wù)是按控制命令的要求、對(duì)功率進(jìn)行放大、變換與調(diào)控等處理，使驅(qū)動(dòng)裝置輸出的力矩、速度和位置控制的非常靈活方便。

伺服系統(tǒng)主要由三部分組成：控制器，功率驅(qū)動(dòng)裝置，反饋裝置和電動(dòng)機(jī)?？刂破靼凑諗?shù)控系統(tǒng)的給定值和通過(guò)反饋裝置檢測(cè)的實(shí)際運(yùn)行值的差，調(diào)節(jié)控制量。

功率驅(qū)動(dòng)裝置作為系統(tǒng)的主回路，一方面按控制量的大小將電網(wǎng)中的電能作用到電動(dòng)機(jī)之上，調(diào)節(jié)電動(dòng)機(jī)轉(zhuǎn)矩的大小，另一方面按電動(dòng)機(jī)的要求把恒壓恒頻的電網(wǎng)供電轉(zhuǎn)換為電動(dòng)機(jī)所需的交流電或直流電；電動(dòng)機(jī)則按供電大小拖動(dòng)機(jī)械運(yùn)轉(zhuǎn)。

永磁交流伺服電機(jī)同直流伺服電動(dòng)機(jī)比較的主要優(yōu)點(diǎn)有：

1、無(wú)電刷和換向器，因此工作可靠，對(duì)維護(hù)和保養(yǎng)要求低。

2、定子繞組散熱比較方便。

3、慣量小，易于提高系統(tǒng)的快速性。

4、適應(yīng)于高速大力矩工作狀態(tài)。

5、同功率下有較小的體積和重量
