控制系統(tǒng)的分類(lèi)有三種方法：以自動(dòng)控制方式分類(lèi)、以參于控制方式分類(lèi)、以調(diào)節(jié)規(guī)律分類(lèi)。
以自動(dòng)控制方式分類(lèi)
1、開(kāi)環(huán)控制系統(tǒng)
若計(jì)算機(jī)開(kāi)環(huán)控制系統(tǒng)的輸出對(duì)生產(chǎn)過(guò)程能行使控制，但控制結(jié)果---生產(chǎn)過(guò)程的狀態(tài)沒(méi)有影響計(jì)算機(jī)控制的系統(tǒng)，計(jì)算機(jī)\控制器\生產(chǎn)過(guò)程等環(huán)節(jié)沒(méi)有構(gòu)成閉合環(huán)路，則稱(chēng)之為計(jì)算機(jī)開(kāi)環(huán)控制系統(tǒng)。生產(chǎn)過(guò)程的狀態(tài)沒(méi)有反饋給計(jì)算機(jī)，而是由操作人員監(jiān)視生產(chǎn)過(guò)程的狀態(tài)，決定控制方案，并告訴控制計(jì)算機(jī)使其行使控制作用。
2、閉環(huán)控制系統(tǒng)
計(jì)算機(jī)對(duì)生產(chǎn)對(duì)象或過(guò)程進(jìn)行控制時(shí)，生產(chǎn)過(guò)程狀態(tài)能直接影響計(jì)算機(jī)控制的系統(tǒng)，稱(chēng)之為計(jì)算機(jī)閉環(huán)控制系統(tǒng)�？刂朴�(jì)算機(jī)在操作人員監(jiān)視下,自動(dòng)接受生產(chǎn)過(guò)程狀態(tài)檢測(cè)結(jié)果，計(jì)算并確定控制方案，直接指揮控制部件（器）的動(dòng)作，行使控制生產(chǎn)過(guò)程作用。 在這樣的系統(tǒng)中，控制部件按控制機(jī)發(fā)來(lái)的控制信息對(duì)運(yùn)行設(shè)備進(jìn)行控制，另一方面運(yùn)行設(shè)備的運(yùn)行狀態(tài)作為輸出，由檢測(cè)部件測(cè)出后，作為輸入反饋給控制計(jì)算機(jī)；從而使控制計(jì)算機(jī)-控制部件-生產(chǎn)過(guò)程-檢測(cè)部件構(gòu)成一個(gè)閉環(huán)回路。我們將這種控制形式稱(chēng)之為控制計(jì)算機(jī)閉環(huán)控制。計(jì)算機(jī)閉環(huán)控制系統(tǒng)，利用數(shù)學(xué)模型設(shè)置生產(chǎn)過(guò)程值與檢測(cè)結(jié)果反饋值之間的偏差，控制達(dá)到生產(chǎn)過(guò)程運(yùn)行在狀態(tài)。
3、在線(xiàn)控制系統(tǒng)
只要計(jì)算機(jī)對(duì)受控對(duì)象或受控生產(chǎn)過(guò)程，能夠行使直接控制，不需要人工干預(yù)的都稱(chēng)之為控制計(jì)算機(jī)在線(xiàn)控制或稱(chēng)聯(lián)機(jī)控制系統(tǒng)。
4、離線(xiàn)控制系統(tǒng)
控制計(jì)算機(jī)沒(méi)有直接參于控制對(duì)象或受控生產(chǎn)過(guò)程。它只完成受控對(duì)象或受控過(guò)程的狀態(tài)檢測(cè)，并對(duì)檢測(cè)的數(shù)據(jù)進(jìn)行處理;而后制定出控制方案，輸出控制指示，操作人員參考控制指示，人工手動(dòng)操作使控制部件對(duì)受控對(duì)象或受控過(guò)程進(jìn)行控制。這種控制形式稱(chēng)之為計(jì)算機(jī)離線(xiàn)控制系統(tǒng)。
5、實(shí)時(shí)控制系統(tǒng)
控制計(jì)算機(jī)實(shí)時(shí)控制系統(tǒng)是指受控制的對(duì)象或受控過(guò)程，每當(dāng)請(qǐng)求處理或請(qǐng)求控制時(shí)，控制機(jī)能及時(shí)處理并進(jìn)行控制的系統(tǒng)，常用在生產(chǎn)過(guò)程是間斷進(jìn)行的場(chǎng)合。
