      本畢業(yè)設(shè)計(jì)課題是屬于教師擬定性課題,主要是研究基于單片機(jī)的對(duì)步進(jìn)電機(jī)的有效控制。步進(jìn)電機(jī)是一種能將數(shù)字輸入脈沖轉(zhuǎn)換成旋轉(zhuǎn)或直線增量運(yùn)動(dòng)的電磁執(zhí)行元件,每輸入一個(gè)脈沖電機(jī)轉(zhuǎn)軸步進(jìn)一個(gè)步距角增量。電機(jī)總的回轉(zhuǎn)角與輸入脈沖數(shù)成正比例,相應(yīng)的轉(zhuǎn)速取決于輸入脈沖頻率。 步進(jìn)電機(jī)是機(jī)電一體化產(chǎn)品中關(guān)鍵部件之一,通常被用作定位控制和定速控制。步進(jìn)電機(jī)慣量低、定位精度高、無累積誤差、控制簡(jiǎn)單等特點(diǎn)。廣泛應(yīng)用于機(jī)電一體化產(chǎn)品中,如:數(shù)控機(jī)床、包裝機(jī)械、計(jì)算機(jī)外圍設(shè)備、復(fù)印機(jī)、傳真機(jī)等。 Abstract This article mainly elaborated has been hanging the movement control system merit, introduced was hanging the movement control system function, the principle and the design process. Is hanging the movement control system is one of in control engineering domain important applications, its main target is to is controlled the object the movement condition, including path, speed and position implementation check. The movement control system compares with other control systems, has the system model simply, the check algorithm is unitary, also not complex characteristic and so on non-linearity and coupling situation. Also is precisely because the movement control system can implement to the path, the running rate, the pointing accuracy as well as the repetition precision ac
