伺服系統(tǒng)由伺服電機(jī)、伺服控制器和反饋裝置組成。伺服電機(jī)的工作原理可以簡(jiǎn)單概括為：輸入控制信號(hào)→伺服控制器→伺服電機(jī)→輸出運(yùn)動(dòng)。伺服系統(tǒng)由伺服電機(jī)、伺服控制器和反饋裝置組成。伺服電機(jī)電動(dòng)機(jī)電動(dòng)機(jī)負(fù)責(zé)產(chǎn)生機(jī)械輸出力和扭矩，編碼器則用于測(cè)量電機(jī)的位置和轉(zhuǎn)速，并將測(cè)量結(jié)果反饋給伺服控制器。通過(guò)不斷比較編碼器的測(cè)量值和控制信號(hào)，伺服控制器可以實(shí)時(shí)調(diào)整電機(jī)的輸出，以保持所需的位置和速度。
