梯形圖程序設(shè)計(jì)語言是用梯形圖的圖形符號來描述程序的一種程序設(shè)計(jì)語言。采用梯形圖程序設(shè)計(jì)語言,程序采用梯形圖的形式描述。這種程序設(shè)計(jì)語言采用因果關(guān)系來描述事件發(fā)生的條件和結(jié)果。每個(gè)梯級是一個(gè)因果關(guān)系。在梯級中,描述事件發(fā)生的條件表示在左面,事件發(fā)生的結(jié)果表示在后面。梯形圖程序設(shè)計(jì)語言是最常用的一種程序設(shè)計(jì)語言。它來源于繼電器邏輯控制系統(tǒng)的描述。在工業(yè)過程控制領(lǐng)域,電氣技術(shù)人員對繼電器邏輯控制技術(shù)較為熟悉,因此,由這種邏輯控制技術(shù)發(fā)展而來的梯形圖受到了歡迎,并得到了廣泛的應(yīng)用。
PLC的CPU性能主要涉及處理器的 "位數(shù)"、運(yùn)算速度、用戶存儲器的容量、編程能力(指令的功能、內(nèi)部繼電器、定時(shí)器、計(jì)數(shù)器的數(shù)量等)、軟件開發(fā)能力、通信能力等方面.在使用特殊功能模塊、特殊外部設(shè)備或是需要網(wǎng)絡(luò)連接的場合,應(yīng)考慮到CPU的功能與以上要求相適應(yīng).此外,在滿足控制要求的前提下,CPU的價(jià)格也是需要設(shè)計(jì)人員考慮的問題之一,選擇的PLC既要滿足系統(tǒng)的功能要求,同時(shí)也應(yīng)該充分利用其功能,避免不必要的浪費(fèi).
運(yùn)動控制,有效的辦法是NC,即數(shù)字控制技術(shù)。這是50年代誕生于美國的基于計(jì)算機(jī)的控制技術(shù)。當(dāng)今已很普及,并也很完善。目前,先進(jìn)國家的金屬切削機(jī)床,數(shù)控化的比率已超過40%~80%,有的甚至更高。
知道了PLC的工作原理后,理解它的語言就比較容易了。PLC語言最常見的有梯形圖和語句表兩種。其中梯形圖又是最為直觀和好用的。要詳細(xì)了解可以看相關(guān)教材,要強(qiáng)調(diào)的是,雖然原理一樣,基本指令也大同小異,但廠家不同PLC指令符號會有所不同,例如,同是上升沿微分,三菱公司的產(chǎn)品用PLS表示,歐姆龍公司卻稱為DIFU,而西門子公司則是│P│。這些具體的區(qū)別就要看各種產(chǎn)品的編程手冊了

根據(jù)動作順序診斷故障。對于自動控制,其動作都是按照一定的順序來完成的,通過觀察系統(tǒng)的運(yùn)動過程,比較故障和正常時(shí)的情況,即可發(fā)現(xiàn)疑點(diǎn),診斷出故障原因。如某水泵需要前后閥門都要打開才能開啟,如果管路不通水泵是不能啟動的。
CPU模塊(包含存儲器)、輸入模塊、輸出模塊、電源模塊等。其他各種智能單元和特殊功能單元也制成各自獨(dú)立的模塊。然后以搭積木的方式將它們組裝在一個(gè)具有標(biāo)準(zhǔn)尺寸并帶有若干個(gè)插槽的機(jī)架內(nèi)構(gòu)成完整的系統(tǒng)??蚣苌嫌须娫醇伴_關(guān),對整個(gè)系統(tǒng)供電。每個(gè)模塊都有彈性鎖扣將模板固定在框架中??蚣苌嫌械刂烽_關(guān),以便系統(tǒng)識別。通常中型或大型PLC常采用這種結(jié)構(gòu)
直接轉(zhuǎn)矩控制直接在定子坐標(biāo)系下分析交流電動機(jī)的數(shù)學(xué)模型,控制電動機(jī)的磁鏈和轉(zhuǎn)矩。它不需要將交流電動機(jī)等效為直流電動機(jī),因而省去了矢量旋轉(zhuǎn)變換中的許多復(fù)雜計(jì)算;它不需要模仿直流電動機(jī)的控制,也不需要為解耦而簡化交流電動機(jī)的數(shù)學(xué)模型。
