1.根據係統的輸入信號
(1)定值調節係統(自動調節係統)
這zhe類lei係xi統tong的de特te點dian是shi輸shu入ru量liang是shi一yi個ge常chang數shu值zhi，通tong常chang稱cheng為wei係xi統tong的de給gei定ding值zhi。控kong製zhi係xi統tong的de任ren務wu是shi盡jin可ke能neng消xiao除chu各ge種zhong幹gan擾rao因yin素su的de影ying響xiang，使shi輸shu出chu保bao持chi在zai給gei定ding值zhi(期望值)。如工業過程中的恒溫、恒壓、恒速等控製係統。
(2)跟蹤係統(追蹤係統)
係(xi)統(tong)的(de)控(kong)製(zhi)輸(shu)入(ru)是(shi)一(yi)個(ge)事(shi)先(xian)無(wu)法(fa)確(que)定(ding)的(de)任(ren)意(yi)變(bian)量(liang)，要(yao)求(qiu)係(xi)統(tong)的(de)輸(shu)出(chu)快(kuai)速(su)平(ping)滑(hua)地(di)再(zai)現(xian)或(huo)跟(gen)蹤(zong)輸(shu)入(ru)信(xin)號(hao)的(de)變(bian)化(hua)。如(ru)雷(lei)達(da)天(tian)線(xian)自(zi)動(dong)跟(gen)蹤(zong)係(xi)統(tong)和(he)高(gao)炮(pao)自(zi)動(dong)跟(gen)蹤(zong)係(xi)統(tong)都(dou)是(shi)典(dian)型(xing)的(de)隨(sui)動(dong)係(xi)統(tong)。
二。線性係統和非線性係統
(1)線性係統

(2)非線性係統
隻要係統中有一個部件的特性不能用線性微分方程描述，就稱為非線性係統。非線性係統沒有完整、成熟、統一的分析方法。通常，當非線性程度不是很嚴重時，或者做近似分析時，可以用線性係統理論和方法來處理。
