1.手(shou)動(dong)(dong)張力控(kong)(kong)制(zhi)器(qi)是指在(zai)(zai)卷(juan)繞(rao)或退繞(rao)過程中，當卷(juan)繞(rao)直(zhi)徑變化到某一階段時(shi)，操作者(zhe)調節(jie)手(shou)動(dong)(dong)電(dian)源裝置來控(kong)(kong)制(zhi)張力。然而，現代凹(ao)印機的手(shou)動(dong)(dong)張力控(kong)(kong)制(zhi)系統已經基本被(bei)淘汰，而只(zhi)是作為閉環自動(dong)(dong)張力控(kong)(kong)制(zhi)系統中的一種運行方式而存在(zai)(zai)。

2.全自動(dong)張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)是(shi)指張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)傳(chuan)感器直接測量料帶的(de)(de)實際張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)值(zhi)(zhi)，然后(hou)將(jiang)張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)數據(ju)轉換(huan)成張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)信號，反(fan)饋給(gei)張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)器。通過將(jiang)該信號與(yu)控(kong)(kong)(kong)(kong)(kong)制(zhi)器的(de)(de)預設張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)值(zhi)(zhi)進行(xing)比較(jiao)，計(ji)算出控(kong)(kong)(kong)(kong)(kong)制(zhi)信號，自動(dong)控(kong)(kong)(kong)(kong)(kong)制(zhi)執行(xing)單元(yuan)使(shi)實際張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)值(zhi)(zhi)等(deng)于預設張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)值(zhi)(zhi)，達到張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)穩定的(de)(de)目(mu)的(de)(de)。這是(shi)目(mu)前先進的(de)(de)張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)方法。此外，在國內生產銷(xiao)售(shou)的(de)(de)中(zhong)高(gao)等(deng)級印(yin)(yin)刷(shua)(shua)機張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)系統中(zhong)，由于印(yin)(yin)刷(shua)(shua)速(su)度較(jiao)高(gao)，生產工藝(yi)對張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)控(kong)(kong)(kong)(kong)(kong)制(zhi)的(de)(de)要求較(jiao)高(gao)，磁(ci)粉(fen)離合器不(bu)再具備作為(wei)該類系統執行(xing)單元(yuan)的(de)(de)資格。因此，在現(xian)代凹印(yin)(yin)機、高(gao)速(su)分切機和高(gao)速(su)涂層復合機中(zhong)，它已被交流和DC伺(si)服電機驅動(dong)器所取代，實現(xian)了更先進的(de)(de)張(zhang)(zhang)(zhang)(zhang)力(li)(li)(li)(li)(li)伺(si)服控(kong)(kong)(kong)(kong)(kong)制(zhi)。
