本畢業設計課題是屬于教師擬定性課題，主要是研究基于單片機的對步進電機的有效控制。步進電機是一種能將數字輸入脈沖轉換成旋轉或直線增量運動的電磁執行元件，每輸入一個脈沖電機轉軸步進一個步距角增量。電機總的回轉角與輸入脈沖數成正比例，相應的轉速取決于輸入脈沖頻率。步進電機是機電一體化產品中關鍵部件之一，通常被用作定位控制和定速控制。步進電機慣量低、定位精度高、無累積誤差、控制簡單等特點。廣泛應用于機電一體化產品中，如：數控機床、包裝機械、計算機外圍設備、復印機、傳真機等。 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: 回答者：網友
